non-string keys (in a BagHash, for example)

[Theo van den Heuvel]

Hi all,

I was hoping to store objects of class Foo in a BagHash in the 
expectation that objects that are "the same" share their keys. But if I 
do something like

my $b = BagHash.new();
for 1..3 {
    $b{['foo']}++;
}
say $b.perl;

#(perl6 version 2014.09 built on MoarVM version 2014.09, Windows 7)

Perl6 considers all entries as new, and the hash has 3 separate entries. 
Do I actually have to project my objects to strings to accomplish this?

Thanks
