Well, it seems ok now:
https://github.com/python/cpython/compare/master...Marco-Sulla:master
I've done a quick speed test and speedup is quite high for a creation
using keywods or a dict with "holes": about 30%:
python -m timeit -n 2000 --setup "from uuid import uuid4 ; o =
{str(uuid4()).replace('-', '') : str(uuid4()).replace('-', '') for i
in range(10000)}" "dict(**o)"
python -m timeit -n 10000 --setup "from uuid import uuid4 ; o =
{str(uuid4()).replace('-', '') : str(uuid4()).replace('-', '') for i
in range(10000)} ; it = iter(o) ; key0 = next(it) ; o.pop(key0)"
"dict(o)"
Can I do a PR?
