Ah. I had assumed that since dead weakrefs were unhashable you couldn't safely use them as keys in a dict. (Presumably removal of a no longer hashable key from a dict is O(n)?) I also hadn't realize that weakrefs were subclassable. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue15412> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
