Éric Araujo added the comment: It could make sense to add clean, working recipes to e.g. the functools documentation. The cached_property in the wiki uses a TTL, other like Pyramid’s reify decorator make properties that ensure the fget function is called only once per instance, and there may be subtly different variants out there. I don’t know if there’s a universally useful variant that should be added to the sdlib right now. (I don’t think a C implementation is needed.)
On a related note, the Python docs about desciptors may be missing entry-level explanations, as described here: http://me.veekun.com/blog/2012/05/23/python-faq-descriptors/ ---------- nosy: +eric.araujo, rhettinger _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21145> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
