I modified ceval.c to accept dict subclasses when I was working on PEP 416: https://www.python.org/dev/peps/pep-0416/ This PEP motivation was to implement a sandbox. The PEP was rejected. Later, I closed my pysandbox beause it was "broken by design": https://lwn.net/Articles/574215/ Paul Sokolovsky wrote in bpo-36220 than his idea is also to implement a sandbox: https://bugs.python.org/issue36220#msg359046 IMHO we should reject dict subclasses to make Python (especially ceval.c) more efficient. The global type must be checked at every place where it's possible to specify or override globals. Like the exec() function. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32615> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
