lue Well, std also says f xx 3 doesn't work, so I'm not sure that's a bug (but it is strange and doesn't feel dwimmy to me). 04:42
grondilu it should work, shoudn't it? 04:43
geekosaur I thought p6 required the ()\
sorear f xx 3 is unlikely to work
geekosaur otherwise you get the 2 terms thing
sorear because after "f" the parser is expecting an infix operator
grondilu isn't xx an infix operator??
sorear geekosaur: if you predeclare functions you can use them without parens
I mean after "f" the parser is expecting a term 04:44

buubot_backup sorear: AAAAA
sorear perl 5 works the same way 04:46
sub foo() being the equivalent of sub term:<foo>
grondilu I guess I must have hallucinated. Or I need some sleep.
sorear lack of sleep can cause hallucinations

mtymula oh tight i've seen that site before

masak g'day, #perl6
mtymula ok so i've got only one q 11:30
masak mtymula: Perl 6 is a language that compiles down to bytecode, not machine code. why do you expect it to compile down to machine code, and why is it a problem for you that it doesn't?
mtymula oh it is not a prolbem for me
i just need to know that stuff for my science work
that i am doing
masak I see. 11:31
well, the reason it's not part of any timeline is that Perl 6 is not chiefly meant to be used that way.
nor is, for example, Java. 11:32
it compiles down to those .class files, which one then interprets.
mtymula good 11:33
masak in Perl 5 and 6, the process is a little simpler, since you don't have to do it in two steps, and you never see the intermediate format.
but the principle is exactly the same.
therefore, .exe files would be a detour. 11:34
huf eventually someone will come up with a way to pack the entire perl6 interpreter and half the world into one single file, along with your code... 11:35
mtymula i am supposed to make a http html app with connection to database and some fancy looking tables on the gui side. My question is, do you know about any deatours or not implemented functionalities that can prevent me from doing that task??
huf that'll be an exe fsvo exe

benabik .shift calls $_.shift, not @_.shift, I think 18:10

.shift always means $_.shift
japhb benabik, I knew that. I just wondered how the two compilers would react.

arnsholt At any rate, func(@array) will never flatten in Perl 6 (unlike Perl 5). For flattening you want func(|@array) 18:32
grondilu it's not really about flattening, it's about mutating, as mentioned in the sentence skids quoted from S06. But I guess I should read this part again more carefully. 18:34
skids S06 also says the "is rw" distributes to the elements of a slurpy, so I read that as the above should have worked.

TimToady we have two different definitions of "flattening" here 18:43
prefix | does one kind of flattening, and slurpy * does a different kind
| flattens an item into the argument list, whereas * manages the transition from positional arguments to variadic 18:44
the term "flatten" is rather badly overloaded 18:45
skids
.oO(that's probably why it's flat, because it got squished)
TimToady to look at it another way, the difference between p5 and p6 is not that we completely did away with item vs list context, but that the decision is made lazily based on binding to the signature 18:46
| lets you violate item-by-item binding on the caller's side, while * lets you violate it on the callee's side 18:47
generally speaking, the * is more normative, while the | is one of those safety valve features 18:49

if then somebody fixes a module than its crap again if you use the release version of rakudo 21:04

spider-mario (or « potentiel »)
« initiation »
grondilu Might be about the number of voyels that follow 't'
spider-mario « différentiation » looks a little like “instantiation” 22:46
except for the e instead of the a
grondilu true 22:47
maybe 't' becomes 's' when followed by two voyels??
(but instantiation would be an acceptable spelling) 22:48
*(but then)
masak I think it comes down to Latin consonant rules when conjugating verbs.
FROGGS masak: got time to look at github.com/rakudo/rakudo/pull/87 ? 22:52
masak sure. 22:54
FROGGS coll
err, cool
masak FROGGS: is it fixing some RT ticket I should also look at?
oh, nvm. 22:55
it's linked from the commit.
FROGGS ;o)

masak is this correlated with the fix STD applied? 22:56
std: do { } for 1
p6eval std d38bbd0: OUTPUT«ok 00:00 43m␤»
masak seems not.
I think I'd prefer a fix that did what STD did to fix this.
22:56 cognominal joined
masak seeing as STD's behavior has changed. 22:57
FROGGS well, is there a do...for ? I thought not 22:59
std: repeat { } for 1

FROGGS at least that is/was still the same
std: repeat { say 42 } for 1

FROGGS std: do { say 42 } for 1
p6eval std d38bbd0: OUTPUT«ok 00:00 43m␤»
FROGGS w/e 23:00
masak I think that's correct, actually. 'do' just makes an expression out of a block or statement.
