Doesn't work: keyword arguments must be listed before * and ** arguments.

SyntaxError: invalid syntax
Personally, I don't see anything wrong with an API of
function(*iterators [, fill]):
Perform function on one or more iterators, with an optional fill
object.
Of course, this has to be defined in code as:
def function(*iterators, **kwargs):
if kwargs.keys() != ["fill"]:
raise ValueError
...
It might not be the easiest API to extend, but for a special case like
this, I think it is perfectly usable.
