Re: [Python-ideas] Default return values to int and float

-0 on proposal, no big judgement (although it might cause issues: if `int` and `float` can take a default, why not `dict` or `Decimal` as well?), but On 2011-10-03, at 11:57 , Chris Rebert wrote:

Why inelegantly?

isinstance(default, (cls, types.NoneType))

is pretty elegant and clearly expresses the type constraint, which is an anonymous sum type[0]. Only issue is that Sphinx has no support for sum types for the moment.
