+= gets something unassignable as the LHS, so fails

Devarishi Hello, world! :) 05:33
Hi Chee! 05:36
moritz o/ 05:37
TimToady we are not the world, but we are #perl6 :)
Devarishi Well, I intentionally said so so that I would know that I am on the right page. 05:38
TimToady what brings you to #perl6? 05:39
chee !
Timbus well perl 6 has no money or women, so it must be Power 05:40
Devarishi To TimToady -> Something inside me... :)
Actually, I am learning Perl 5 day and night these days.
TimToady my condolences :) 05:41
Devarishi I thought I would be part of this community.

Devarishi So, how can I get involved even though I am an intermediate student of Perl working on Linux as a Software Engineer.
TimToady there are many ways to get involved 05:42
Devarishi I am afraid. I am not a master yet. Can I still get involved?
TimToady testing, docs, testing, testing, and just trying things out
Devarishi Right!
TimToady and demonstrating which things are easy and which things are hard
Devarishi Reading docs and writing scripts. 05:43
Can you elaborate "testing"?
TimToady both formal and informal
Devarishi Do you mean "Writing Perl scripts" or do you mean testing what we see on the official site?
TimToady formally, Perl 6 is defined by the test suite
Devarishi Okay.
TimToady informally, anyone writing Perl 6 is testing it 05:44
Devarishi I got your point!
TimToady writing examples for rosettacode.org, for example, is an informal way of testing
Devarishi So, will my understanding of Perl 5 help me?
TimToady we already have 406 running examples on rosettacode
yes
chee lol i love Devarishi
05:45 am0c joined
Devarishi Chee -> What made you do that? :) 05:45
TimToady the details are different, but the overall philosophy is the same
05:45 kaleem joined
Devarishi I am checking out the site you pointed to. 05:45
TimToady and by an large, if you try something P5ish, and it's not P6ish, the compiler will tell you 05:46
you'll also want to follow the doc links from perl6.org
Devarishi Well, i just read the official site that we can include P5 and P6 at will.
TimToady well, that's is a long-term goal
chee Devarishi: you have cheery disposition. it was what made me do that

Devarishi Tim -> At first I found Perl time-consuming as I used to write Web Pages in PHP. Specifically when I wrote some CGI in Perl. When we POST form data it is easier to handle them using PHP, for example, than in Perl.
05:50 Trashlord left
TimToady so P6 tries to help you translate from P5 to P6 05:51
Devarishi But then I realized the Power of Perl in text processing.
TimToady Perl is more of a general language
Devarishi Will P6 provide easy mechanism for CGI and Form Data hnadling?
TimToady there's already some work on that from various folks
moritz perl 6 provides enough features so that module authors can do such things 05:52
TimToady and it's really easy to mutate Perl 6 into whatever language you really want
Devarishi That's good news.
TimToady (at least, that's a goal)
Devarishi Thanks Tim and Chee! I will stay in touch with you people here. 05:53
TimToady the language itself is parsed with Perl 6 grammars, so it's really easy to tweak with more Perl 6
have fun!
Devarishi I am in office and have to take care of some release stuffs assigned to me. Have a nice time! 05:54

TimToady the assumption is that you can't speak for subclasses

moritz masak: it easily generalizes to variable O's :-)
masak :)
yes, but not both. 10:17
moritz somebody please port Algorithm::Loops to Perl 6 :-)
masak I'm pretty sure this can be written as a sequence operator somehow.
moritz I'm pretty sure there's an elegant solution that just counts up to the number of permutations, and calculates the indexes of the Xs with modulo somehow 10:19
grondilu: you can, but it's probably not quite trivial 10:20

TimToady because there's no overhead to multiplying by 1 in pure math? 15:31

TimToady all of the above, probably, and also because they're just used to seeing factorial defined that way 15:32
sjn it's also a case of "value of clarity" > "value of computational gains"
TimToady and perhaps because pure math doesn't define product of a null range? or does it? 15:33
that too
sjn *shrugs*
TimToady so maybe someone just throws a small optimization in the compiler for that instead of teaching people that the 1 is a waste 15:34

17:41 kmwallio joined
sjn tadzik: would you come? :) 17:42
sjn has updated gist.github.com/1711730
17:43 robins is now known as robinsmidsrod
sjn krunen: feel free to join in when you can :) 17:43
tadzik sjn: if I lived closer, for sure :)
sjn tadzik: where do you live?
tadzik sjn: Warsaw, Poland 17:44
sjn what
that's pretty close
sjn bets there's a lot of cheap flights between Oslo and Warsaw :) 17:45
tadzik oh, stop tempting me :>
tadzik checks out the flights
sjn tadzik: I find a flight for €90 17:46
tadzik that's not cheap by my standards :) 17:47
sjn tadzik: if you buy that ticket right now, I'll promise you a sofa to sleep in :)
tadzik I'm but a poor student :)
daxim apply for sponsoring 17:48
tadzik hmm
a ferry, maybe
sjn tadzik: btw, your ircname doesn't say you real name
tadzik it does
Tadzik is a short from Tadeusz, which is my real name :)
sjn tadzik: ah :)
tadzik: and may I have your surname? :) 17:49
tadzik :) it's Tadeusz Sośnierz
sjn takes notes*
tadzik is that for some beautiful girl?
:P 17:50
sjn tadzik: as it happens, I have a short-list of people we should help sponsoring the trip, and you're on it :)
if you want to come
daxim I found a flight for 290 PLN/wizz air
tadzik why, of course I want :)
sjn can't promise a full refund, but we'll do what we can
and €90 should be no problem
tadzik: www.dohop.no/flights/?a1=WAW&a2...;d2=220412 17:51
tadzik wow, that's awesome
oh, that's 90€ with a return?
sjn that super cheap price is maybe a bit inconvenient
yes, it's with return
tadzik 384 PLN both sides is something I can affort 17:52
sjn but it arrives very late
tadzik s/t$/d/
17:52 spine_ left
tadzik as long as you don't mind, I'm fine with being a bit late :) 17:52
sjn that's ok :) 17:53
tadzik phenny: "Lavpris"? 17:54
phenny tadzik: "Low" (da to en, translate.google.com)
sjn tadzik: you can change language on that page
top-right of page 17:55
tadzik thanks :)
sjn pmichaud: any chance for you to take a trip to Oslo in April? :) 17:56
tadzik there's also a flight on Thu, that won't make me late for Friday Social Event
skids Don't I remember reading somewhere that grammars could have class-like attributes/variables in them in addition to rules? Can't seem to find that in spec (maybe just blind.)
sjn tadzik: if you prefer that one, it's fine... I'll be quite busy on friday daytime though 17:57
it might give you a day for doing touristy stuff
tadzik yeah, I'm thinking about that
17:58 tarch left
tadzik I'm looking at the plan for the next semester, and on friday I'd probably be having only one classes, and possibly reschedulable 17:58
sjn tadzik: don't think for too long :) 18:01
tadzik I'll just wait for an exam session to end, and to make sure how my weekly schedule will look like 18:07
in the best case, that'd be friday 18:08
or something friday-ish
sjn tadzik: ok, just beware that flight prices are likely to rise :-/ 18:10
tadzik sjn: awesome thing, thanks for an invitation :) 18:11
sjn: yeah, I know that
sorear things which have been sent my way so far today: constant folding SORRY opportunities, line number LTAness, Proxy, overriding termy things 18:13

sjn (oh, and if anyone else is interested in gist.github.com/1711730, get in touch with me :) 18:20
[Coke] sjn: looks nifty. 18:21
are the damian classes sixian or fivish?
sjn fivish
no decisions yet though
depends on what the local companies want 18:22
colomon sorear: there's no urgent need for Proxy, mind you, I just can't figure out how to implement KeySet (and probably KeyBag) without it, other than by calling an O(N) function an obscene number of times in the code: gist.github.com/1712021
[Coke] colomon: do it, we can pass MOAR SPEC TESTS! MUAHAHAHAHA 18:23
colomon [Coke]: I could already check in what I've got, it already passes a bunch of new KeySet tests I've written. It's just -- ugly. 18:24
sorear: speaking of which, we're getting a lot of fail in Set/Bag/KeySet/etc tests because of difficulty assigning them to %-sigiled variables. 18:25
sorear assignment to %-variables is not very magical. The RHS needs to evaluate to a list of pairs in list context, that is all 18:29

skids ...? Where'd the first match go? 19:49
sorear [Coke]: niecza doesn't currently have a 'StrPos'. But a lot of the StrPos tests are veyr dubious.
[Coke] sorear: we pass a lot of them, considering we don't have StrPos. ;)
(I noticed the message because an auto-unfudge gave us passing TODOs) 19:50
sorear I should think that the first job of a test is to fail when the tested feature doesn't exist at all.
[Coke] I'll leave it alone for now.
sorear: well, presumably you wouldn't auto-unfudge that one.
