[Dong-hee Na]

New submission from Dong-hee Na <donghee.na at python.org>:

+-----------+------------------+----------------------+
| Benchmark | map_bench_master | map_bench_vectorcall |
+===========+==================+======================+
| bench map | 151 ns           | 116 ns: 1.30x faster |
+-----------+------------------+----------------------+

We already apply this feature for filter().
No reason not to apply map().
