Feature or enhancement

Proposal:

It seems that a typecheck can be added as suggested by the existing comment

    def __new__(cls, days=0, seconds=0, microseconds=0,
                milliseconds=0, minutes=0, hours=0, weeks=0):
        # Doing this efficiently and accurately in C is going to be difficult
        ...

        # XXX Check that all inputs are ints or floats.

Currently, an error is raised, but it's not explicit that it's because of an argument of wrong type

_pydatetime.timedelta(seconds='1')
# TypeError: can only concatenate str (not "int") to str

If this type check is not desirable, I think we can simply remove the comment.

Has this already been discussed elsewhere?
