I have run into a use case where I want to create a wrapper object that will star-unpack a sequence of arguments to pass to a function. Currently one way to construct this is to create a function:

Such a function feels simple enough, and specific enough to the language, that it would fit in well in the operator module of the standard library. We already have a similar representation of this functionality in itertools.starmap.

Whereas the nested function implementation above will produce unpickleable objects (due to the closure), a straightforward c implementation will produce pickleable ones, making them useful for parallel applications.

Thanks,
