So, just for fun I added the following test to t/pmc/perlhash.t:
new P10, .PerlHash
new P1, .PerlString
set P1, "Bar"
new P2, .Key
set P2, P1
set P10[P2], "Food\n"
set S0, P10[P2]
print S0
new P3, .Key
set P2, P1
set S1, P10[P2]
print S1
end
Just to test that two Keys created from the same PMC would fetch the
same thing from the hash.
Imagine my surprise when the test blew up with 'Key not a string!'
before producing any output.
Perl 6 supports using full on objects as keys in its hashes. It seems
that having parrot do the same would be a Good Thing.
