This is certainly the right place to discuss this, but you shouldn't 
assume that everyone reading will know what powerset functionality you 
are referring to.

Is it the same as the recipe in the itertools documentation?

https://docs.python.org/3/library/itertools.html#itertools-recipes

Can you make a case for why it is important and useful enough to be put 
into the std lib? Every new function increases the burden on both the 
Python developers maintaining the stdlib, and new users learning to use 
the language. So you need to make a case for why the benefit outweighs 
the costs.
