That sounds like a worthwhile optimization. FWIW, is this a bit simpler but
sufficient?:
python -m timeit -n 2000 --setup "from uuid import uuid4; \
o = {uuid4().hex: i for i in range(10000)}" \
"dict(**o)"
Is there a preferred tool to comprehensively measure the performance impact
of a PR (with e.g. multiple contrived and average-case key/value sets)?
