current behavior of isa method on a subset: % perl6 -v This is Rakudo version 2017.08-110-g5f3350656 built on MoarVM version 2017.08.1-156-g4 9b90b99 implementing Perl 6.c. % perl6 -e'subset S of Int; say S.isa(Int)' Cannot resolve caller isa(Perl6::Metamodel::SubsetHOW: S, Int); none of these signatur es match: (Mu \SELF: Mu $type, *%_) (Mu \SELF: Str:D $name, *%_) in block <unit> at -e line 1 The documentation https://docs.perl6.org/routine/isa implies this should return True.
