Can we have it return a string instead, and then hash the string?
Strings tend to be able to carry more data--how do you come up with an
integer ID for this?
new Math::BigFloat('3.1415926535897932384626433832795');
While it may not make much of a difference for things like aggregates:
ARRAY=0xDECAF
It'll be quite useful for value types:
Math::BigFloat=3.1415926535897932384626433832795
which often can't be adequately expressed as an integer while still
having different instances of the same value be equivalent.
Beyond that, I would like to specifically request that PMCs *not* hash
themselves. They should return a value that the aggregate hashes. That
makes it much easier to change the hashing algorithm later.
