I'd place additional requirements on using bin/oct/hex for this:
1. The new feature must be available to floating point types other than
float (such as Decimal) in both 2.6 and 3.0 (keeping in mind that 3.0
does not support __bin__, __hex__, or __oct__ methods - it uses only
__index__ to implement bin(), hex() and oct()
2. Other classes (such as Decimal) should be able to leverage the
formatting functionality provided for floats.
If it was just a new method on float objects or a new function in the
math module, neither of those additional requirements would apply - I
would be completely fine with the function only working for actual float
objects.
However, in either case, I think this also runs afoul of the "we're in
beta" argument - yes, it's a nice feature, but I don't think it's one
that will cause any great dramas if users don't get their hands on it
until 2.7/3.1.
Cheers,
Nick.
