BenGoldberg, Output on both points:
MasterDuke BenGoldberg: do you get any different results if you alter the signature earlier, e.g., at BEGIN or INIT time? 01:46
BenGoldberg To be honest, I'm glad that alterning the signature *doesn't* change things... I want to wrap a subroutine like so: my $wrapped = sub (|args) { my $*foo = $bar; $orig(|args) };, and then change the signature of $wrapped to match the original's. 01:49
While it's convenient for me, I'm vaguely worried that it might change in the future. 01:50

BenGoldberg I expect that '$!signature' is only used when Code objects are created -- everywhere else, the method .signature is used instead. 01:54

geekosaur j75_, the lack of error message suggests to me the OOM killer got it 06:10
sammers is this behavior for `constant` correct? When I run this in the repl, the second run doesn't run the sub...

sammers sorry for the spam
j75 geekosaur: thanks, just checked dmesg I think you are right 06:14
geekosaur sammers, "constant" operates at compile time, and %subs is empty then
sammers ok, after creating %subs, then running "foo.("bar");" from a new repl line it works. 06:15
geekosaur right, that'd make sense for how the repl operates 06:16
sammers ok, thanks
is there any way to do something like this and execute the code block assigned to %subs<foo> without using foo.()? 06:17
like, something that lets me use "foo: .." or just "foo $param"?
geekosaur m: BEGIN my %subs = foo => -> $bar { say "Hello, $bar" }; say "1st run"; %subs<foo>.("bar"); constant foo = %subs<foo>; say "2nd run"; foo.("bar"); 06:24
camelia 1st run

geekosaur but for the .() I think you may need to play with hacking CALL-ME into it :/
sammers hmm 06:25
BenGoldberg m: sub foo ($bar) { say "low $bar" }; foo "param";
camelia low param
BenGoldberg It should be pretty easy to create a module with an import method, which takes a hash (your %subs), and then mucks with %CALLER so that perfectly ordinary subs are produced. 06:27
But, since it's late enough in my time zone that it's almost early, I've gotta go. 06:28
sammers how do I send a note to another user again? 06:28
j75 [irc] /msg [-server <server>] <target>[,<target>...] <text> 06:30
geekosaur or for yoleaux, .tell nick message 06:31

IOninja is fine with that 14:27

masak is happily surprised to find tio.run/nexus/perl6 14:41
timotimo what's the "header" and "footer" thing about? 14:43
masak no idea 14:45
moritz looks to be simply code that's concatenated to the "code" input field 14:53
if I define a variable in the header, I can access it in the footer
no idea why one needs separate input fields for that though
IOninja likely for markup
I assume Perl 6 isn't the only language on the site. 14:54
moritz maybe to be able to collapse parts you don't want to show

though no idea how to make it handle type smileys
IOninja stashes this one for a rainy day...
jnthn We'd need to spot it's a concreteness type and pull out hte real type to do the .new on 15:48
Though I'm curious why we're ever using the string there 15:49
Feels a bit odd, since we should be letting type parsing make an AST with the right kinda thing, I'd hope

jnthn Thought so...
IOninja aww :( 16:00
jnthn At the time $!foo is read in BUILD it hasn't been initialized
So $x contains the Any type object
And so it's doing 42 ~~ Any
Also even if a binding were used, it'd still be referring to the attribute of the latest instance of the object 16:01

IOninja raschipi: well, it's $foo.bar: <some args>; But we have the meta-assign op; in other languages you may seen it as $x += 42, which is the same as $x = $x + 42; We extended that metaphore to all operators, so you $x .= foo: <some args> is the same as $x = $x.foo: <some args>; (which is same as $x = $x.foo(<some args>) 16:43
raschipi I know how it works, I understood the code. But I got it from code examples and wanted to see the docs for it. Can't find it. 16:44
IOninja Ah. No idea where that may be documented. 16:49
IOninja There's a blurb here: docs.perl6.org/routine/$FULL_STOP$EQUALS_SIGN 16:52

IOninja Something like `my %h = :42a, :72b; for %h.pairs ---> { say $:key, $:value }` to mean call it as `for { {}(|$_) }` 17:09
raschipi I see
IOninja Which can be generalized to signature thingie on all callables that would know to slip the given argument, so instead of doing |(blah blah) on each call, you'd specify it once in the signature. 17:10
Or maybe not, since we can do slurpies right now \o/ 17:11
