[Python-Dev] return type of __complex__

[Greg Ewing]

I think I've changed my mind on this, since it was pointed
out that if you're going to return a float instead of a
complex, you should really be implementing __float__, not
__complex__.

So I think it's fine to require __complex__ to return a
complex, and the docs should perhaps be clarified on that
point.

Also PyComplex_AsComplex() should perhaps enforce that.
