hello - I have a question about name lookup ... this works vvv 14:41
m: class C::X { has $.y=42 }; role R[$x='X'] {method new {C::X.new}}; dd R.new;
evalable6 C::X.new(y => 42)
Raku eval C::X.new(y => 42)
librasteve (phew, it worked) 14:42
but this fails vvv
m: class C::X { has $.y=42 }; role R[$x='X'] {method new {C::($x).new}}; dd R.new;
Raku eval Exit code: 1 ===SORRY!=== Error while compiling /home/glot/main.raku Combination of indirect name lookup and call not supported at /home/glot/main.raku:1 ------> 2 }; role R[$x='X'] {method new {C::($x)⏏.new}}; dd R.new; expecting any of: argument list

librasteve, Full output: gist.github.com/3a4d697ba1dc1f30fc...a74af2d502
librasteve what I am doing wrong?
oh - I have worked it out... vvv 14:48
m: class C::X { has $.y=42 }; my $x= 'X'; dd C::{$x}.new;
evalable6 C::X.new(y => 42)
Raku eval C::X.new(y => 42)
nemokosch yeppers
m: class C::X { has $.y=42 }; role R[$x='X'] {method new {C::{$x}.new}}; dd R.new;
evalable6 C::X.new(y => 42)
Raku eval C::X.new(y => 42)
librasteve thanks! 14:49
wonder what happens if I use ≪≫ [oh so funny joke] 14:50
nemokosch not sure if we want to see that 14:55
oh right, somebody said that %hash<<$key>> would be an allomorph-based lookup. Fortunately that's not the case. The base implementation coerces the key into the exact Str type 14:57
one would wonder what happens for an "object hash" 14:58
m: my %demo{Any}; %demo<12> = 5; %demo.keys.&dd; %demo{12} = 99; dd %demo; 14:59
evalable6 (IntStr.new(12, "12"),).Seq
Hash[Any,Any] %demo = (my Any %{Any} = IntStr.new(12, "12") => 5, 12 => 99)
Raku eval (IntStr.new(12, "12"),).Seq Hash[Any,Any %demo = (my Any %{Any} = IntStr.new(12, "12") => 5, 12 => 99)
nemokosch this one does do allomorph-based lookups, even with the single angular brackets 15:00
looking at the behavior, I rest my case, honestly
librasteve m: my %demo{Any}; %demo≪12≫ = 5; %demo.keys.&dd; %demo{12} = 99; dd %demo; 15:01
evalable6 (exit code 1) 4===SORRY!4=== Er…

nemokosch it probably wasn't the one
librasteve maybe Discord is manlging my unicode 15:05
anyway, all rakoons should know that angle brackets autoquote stringy literals and make allomorphs out of numeric literals, right? 15:07
when you know that the hash behaviour you illustrate is self evident (just putting two familiar things together) 15:08
(or would you rather have different behaviour for angle brackets when used for associative indices?) 15:09
you certainly haven't said anything yet that will make me think removing allomorphs from raku is a good idea 15:10
;-)
nemokosch it seems like you would reject any sort of evidence 15:11
I don't find it a healthy attitude to always just say to whatever that can cause problems more often than not that one can just learn them and then suddenly it's all fine... 15:13

if there is a way to dump sub signature in a nice way? like Data::Dumper does? 18:31

[Coke] If you want a pretty printer, you'll have to write one.
