Okay, that's a good enough justification for me.

We should be all set; I discussed this a bit with Gustavo this morning.
The locale-safe versions of float() and str() should live in locale [*],
and semantics for float() and str() stay unchanged.

[*] Is there a reason why we only have atof() and not float() in locale?
I'm asking because we *do* have str().  Would=20

    locale.float =3D locale.atof
be a good idea, for consistency's sake?
