Yes. But first import time is also important for CLI applications. That's why mercurial and Bazaar has lazy import system. Since many stdlib uses functools, many applications may be suffered from slow functools import even if we remove it from site.py. > maybe we don't have to copy the entire namedtuple structure? https://docs.python.org/3.5/library/functools.html#functools.lru_cache The doc says it's a namedtuple. So it should be namedtuple compatible. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28638> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
