From @usev6

On the JVM backend the coercion type returned from .keyof for a regular hash is not the same object as Str(Any)​:

$ ./perl6-j -e 'use nqp; say nqp​::eqaddr(Str(Any), {"a"=>1}.keyof)' 0

$ ./perl6-m -e 'use nqp; say nqp​::eqaddr(Str(Any), {"a"=>1}.keyof)' 1

That's why some tests in S09-typed-arrays/hashes.t and S32-hash/perl.t have a new failure mode after fixing RT #​132673. The objects are compared with infix​:\<===> from Any.pm and that uses nqp​::eqaddr. [1]

$ ./perl6-j -Ilib -e 'use Test; is({"a" => 1}.keyof, Str(Any))' not ok 1 - # Failed test at -e line 1 # expected​: (Str(Any)) # got​: (Str(Any))

I'm opening this ticket in order to update the todo message of said tests.
