lizmat I guess we could lift that with a "no isms <C++>" 08:52
ZzZombo I wonder why is there no "Unsupported use of Object Pascal constructor: in P6 use Foo.new instead of Foo.Create". 08:55
Or for any other language.
lookatme_q There are some prevent you using some syntax such as -> 08:56
I don't know if it fixed 08:57
08:57 graphene left 08:59 graphene joined 09:00 p6bannerbot sets mode: +v graphene
ZzZombo well, it's one thing to forbid unsupported (invalid) syntax, even tho I don't really agree with mentioning C++ or any other language for that matter. It's another going out of your way to forbid valid syntax just because some other language also uses it (?). 09:00
AlexDaniel it was meant to be helpful in case somebody writes that by mistake… A for effort I guess :) 09:03
lizmat I suggest we implement "no isms <C++>" 09:04
and then consider making "no isms" a default for 6.e
AlexDaniel .e? Doesn't have to be that far I think 09:05
well, as long as there's enough devpower to make that happen earlier 09:06

Zoffix AlexDaniel: 6.e isn't "that far" really. We won't be waiting 3 years for it. Probably do it yearly, if it's worth it. 11:11
And probably do the work for it on an ongoing basis. Just so there isn't 3000 commits to review by the end. 11:12
And I imagine somewhere by [middle of] October there will be a changelog for 6.d released to users, and that would basically be a cutoff for all 6.d features. 11:13
Switching to "6.e" as our new go-to version for new features isn't a bad a idea :)

louisono hi, I'm trying to learn perl6 can anybody help me? 14:52
timotimo hello louisono
we have many different ways to learn perl6, depending on how you like to learn 14:53
louisono actually I'm reading a book
timotimo oh, cool, so you've already got something in front of you
louisono Perl6 Fundamentals
14:53 robertle left
timotimo i think i have that in my bookshelf as well 14:53
do you have a particular question? 14:54
louisono yes. At some point in the book's code there a double semi-colon ';;' at the end of a line
I was wondering what it meant?
14:55 yqt joined
timotimo if i'm not forgetting something, double semicolons are only ever relevant inside of parenthesis when you're declaring a sub 14:55
so it's probably just a typo
14:56 p6bannerbot sets mode: +v yqt
louisono at first i thought it was a typo but then when changing the code the double semicolon happens again at an equivalent place in the code 14:56
timotimo if you remember the page number i can take a closer look
louisono thanks! it is at the end the chapter about testing page 35 14:57
timotimo yes, that looks just like a typo 14:58
it's not a mistake, it's just meaningless there
louisono ok, thanks for your help :)
timotimo moritz: ^ in case that's not already in your bugtracker or what you have 14:59
feel free to stay around or come back for when you have more questions :)
louisono thank you for welcoming newcomers such as me so nicely! 15:00

Zoffix ccc_: the `(1,2,3) eqv [1,2,3]` is false, because one is an immutable List, while the other is a mutable Array. The item thing places things that are collections of many items (like lists) into a Scalar container, so that the entire collection gets treated like a single entity in things like looping or list flattening. There's an article on containers: perl6advent.wordpress.com/2017/12/02/ 16:19

TimToady xinming: no, because junctional infixes | and & are also valid signature characters due to lack of TTIAR policy there 19:05

TimToady you can, however, use a subset type there 19:06
when you use a subset type in a signature it automatically splits out the 'where' bits for you

let me know if you need any help at any part
also, on your installation issues, I'd recommend making an issue on the zef repo

lichtkind tyil thank you but looks like i should get along, Matrix.gist is just currently broken badly so i have to fix that first, the blocker of 0.3.0 19:39

Zoffix .tell lucasb but there's no error in that code (other than overobundance of characters). The `a %% b` operator is equivalent to `a % b == 0`, so the code does indeed check for odd numbers: `m: my $number = 3; if ! $number %% 2 { put 'The number is odd' }` 20:57

lucasb ^^ that would be a very orthogonal feature to have! :) 22:55
since booleans are treated as numeric 0 and 1, why not have metaoperator ! and allow numerics to be treated as booleans 22:56

TimToady we just decided that making the ! metaop coerce to boolean was one step too far 23:15
if we made ! coerce, we'd also have to make ? coerce, and that's just, well...two steps too far 23:16

timotimo ah, looks like you're passing the headers as a literal hash, but the subs expect to get it slipped in 23:52
i.e. a bunch of named arguments, or alternatively |%the-header-hash
perlBird that seemed to do the trick!
I was way overthinking it lol 23:53
timotimo hum, but the synopsis looks different
ah i was looking at the wrong one
perlBird now I'm just getting a 400 error, but i expect I just don't understand how WWW wants the JSON to come 23:55
timotimo are you familiar with network sniffers like wireshark? or you can just use strace which is much simpler to get running, but a bit noisier to look at 23:56
perlBird never really used anything of the like 23:57
