Good point, so s/reals/complex numbers/ -- except for this "detail",
Mike's idea do seem well founded.
What *I* would also like would be a basenumber abstract class, like the
existing basestring, such that alternate numerics (like those I supply
in gmpy) could inherit from it in order to assert "yes, I *AM* a
number!" and allow isinstance-based checks rather than ones based on
"try to sum 0 and see if that gives an exception". A very small,
localized, and potentially useful change, IMHO.
