Well, the more general question is: how can we parameterize our
aggregates. We already have tons of arrays with (bit, double, int, PMC*,
STRING*) values.
For hashes it could get worse:
key / value
STRING* / PMC* Hash
PMC * / PMC * Python / Perl6
&PMC / INTVAL ref hash
x y Perl6
The hash functions in src/hash.c can handle this (probably), with
key/value type and with user defined compare/hash functions already
inside..
We need an interface above that constructs appropriate vtable pieces for
key and value access from the PMC side.

For now c&p helps :-)
