New submission from Dong-hee Na <donghee.n...@gmail.com>:
Since PEP 560 was approved, The following syntax has become available. from queue import Queue v = Queue[int] It's a very shiny feature. Given the direction of programming language, it's probably a very useful feature that users will use very often in the near future. When I looked at Object/geneticiasobject.c, the current implementation is a very good condition for using the vectorcall proposed by PEP590 . The benchmarks are as follows. So I suggest using vectorcall in GenericAlias. if the suggestion is accepted, I 'd like to summit the patch :) +--------------------+----------------------+-----------------------------+ | Benchmark | master-generic-alias | proposed-generic-alias | +====================+======================+=============================+ | bench GenericAlias | 143 ns | 111 ns: 1.29x faster (-22%) | +--------------------+----------------------+-----------------------------+ ---------- components: Interpreter Core files: bench_generic_alias.py messages: 367074 nosy: corona10, gvanrossum, vstinner priority: normal severity: normal status: open title: Use PEP 590 vectorcall to speed up GenericAlias. versions: Python 3.9 Added file: https://bugs.python.org/file49087/bench_generic_alias.py _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40369> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
