> The problem with using STORE_MAP is you create a new dict for each keyword argument in that situation.

You don't; if you look at the disassembly for producing a built-in dict ("dis.dis('{1:2, 2:3, 3:4}')") you'll see they use STORE_MAP too. STORE_MAP seems to just be the map equivalent of LIST_APPEND.

I've done simple timings that show my version being faster...

Unfortunately, it points out there is definitely a memory leak. This reproduces:

    def f(a):

    while True:
        f(**{}, a=1)

This goes for both patches 8 and 9.
