Context: I am trying to make a fun syntax where Class[@args] is an alias for Class.new(@args) ----- class C {}; sub postcircumfix:<[ ]>(C:U $c, Str $arg){ say 'win' }; my $c = C; $c['test']; #-> win C['test']; #!> C cannot be parameterized ------ I also tried: ------ role R { method parameterize(|) { say $*d; } }; class C {}; BEGIN { C.HOW does R }; my $*d = 'win'; C[my $a = 'test']; #-> win C['test'] #!> Dynamic variable $*d not found ------ But I can't use dynamic variables because if it's called with a compile time variable it runs .parameterize at compile time only. I tentatively suggest that at least one of these is a bug as they together prevent you using [] on a type to callback to something using $*dynamic variables consistently.
