Coercing two numbers without coerce()

[Luciano Ramalho]

Python 3 dropped the coerce() built-in, but I have a situation where
I'd love to use it.

I have two numbers A, B and I need to get the value of A coerced to
the type of A+B. This is for a generator function that will produce a
series similar to what itertools.count does.

I know I can do type(A+B)(A), or A+B-B, but both alternatives are ugly
and perform needless arithmetic.

What do you suggest, now that the coerce() built-in is not available?

Cheers,

Luciano
