Sorry, I don't remember all the constraints. Read the code and weep. This should be revisited for Py3k. The code became convoluted out of some needs in Zope; I can't remember if it was Zope 2 or Zope 3 that needed this (probably both) and I can't remember the specific situation where it was needed. -- --Guido van Rossum (home page: http://www.python.org/~guido/) _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
