Guido van Rossum <gu...@python.org> added the comment: Hm, so the extra pointer is a feature. I guess a compromise would be to keep the extra indirection but make it point into the same object in the base class. Thinking about how memory caching in modern CPUs work, this would probably be quite fast but it would still cost 8 bytes on most future (i.e., 64-bit) architectures.
Still, I expect that a vanishingly small number of users will actually use that feature. Is it worth to make everyone pay for that flexibility, for what must be the first- or second-most commonly used type in Python 3.x (the other being int), which is still significantly slower than the common (8-bit) string type in 2.x? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue1943> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
