One reason is that abstract base classes are relatively new (Python 2.6) and the work hasn't been done to put them in place. It will require a bit of thought about how best to use them within Sage. For example, I don't think we want isinstance(i, Integer)
to be True
since in Sage Integer
is a concrete class wrapping an MPIR mpz_t
. However, you could register Integer
as numbers.Integral
and then test against that.
