tbrowder hi, anyone using windows using scoop for installing? if so, does it have any raku packages? 11:10

arkiuat I keep getting "Default constructor only takes named arguments" even though MyClass.^can('new') returns (new new), so the second multi method (which takes positional args) is there 13:54
although that's odd two, because I made two multi-method-news so in addition to the default named-parameter .new() there ought to be three in that listing 13:55
s/odd two/odd too/
oh, checking the .arity on the two .new methods, they both show .arity 1, so those are both named-parameter, both inherited. So at least I know that that neither of the multis I added are showing up in the call chain 13:58
Introspection is pretty cool 13:59

lizmat arkiuat: if you can provide a gist re your .new issue, we could have a look to see what's wrong 16:46
arkiuat if I don't find my own silly error while trying to golf it down to a single-issue snippet, I'll keep that in mind and post one for y'all. But I may not get a chance to work on this again until Monday or even Tuesday 16:47

lizmat the problem in those cases is usually that the signature of your own .new doesn't match with what you think it should 17:02
an easy test case is to temporarily remove the "multi" from the "multi method new" and see what error that generates

arkiuat lizmat: that's a great tip, thanks! it not only immediately revealed my problem here, but i've been stumped by this same error message before, and I bet it would've helped all of those times too 20:18
lizmat you're very much welcome :-) been there, done that :-)
disbot4 <vendethiel> o/ 20:20
<vendethiel> m: my class A { has $!x; }; my $a = A.new(x => 10); my @a = A.^attributes; @a[0].get_value($a);
<Raku eval>
lizmat m: my class A { has $!x; }; my $a = A.new(x => 10); my @a = A.^attributes; say @a[0].get_value($a); 20:21
disbot4 <vendethiel> is that meant to be possible? can I make it available?
camelia (Any)
lizmat m: my class A { has $.x; }; my $a = A.new(x => 10); my @a = A.^attributes; say @a[0].get_value($a);
camelia 10
lizmat make it public?
m: my class A { has $!x is built; }; my $a = A.new(x => 10); my @a = A.^attributes; say @a[0].get_value($a);
camelia 10
lizmat or make it sure it's being built
disbot4 <vendethiel> I want to provide force-include/force-exclude is traits for my serialization module 20:22
<vendethiel> I can forcefully call trait_mod:<is>($a, :built); I guess
<vendethiel> thanks! 20:23
<vendethiel> I need to read up on is built cause I don't remember anything about it 20:25
lizmat basically it allows you to more options with regards to automatically creating accessors and/or accepting values to initialize with 20:39
$!x is built does not create an accessor .x but it does allow you to initialize x with .new 20:40
