[New-bugs-announce] [issue43287] Use PEP 590 vectorcall to speed up calls to filter()

[Dong-hee Na]

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

+--------------+--------+----------------------+
| Benchmark    | master | vectorcall           |
+==============+========+======================+
| bench filter | 191 ns | 151 ns: 1.26x faster |
+--------------+--------+----------------------+

Like reversed(https://bugs.python.org/issue41922), it looks okay to update filter() to use PEP 590.
