Having a fast hash instruction might help: It would take two numbers
as arguments and produce a single number that is a hash of the pair.
It would not need to be cryptographically strong, just good enough for
hash tables.
This can be used for associative arrays, dynamic method lookup for
clone-based inheritance, etc.
A good hash can take many "normal" instructions, but you can make a
good hash efficiently in hardware.
