It would provide no speed advantage, and I don't see how the staticness would be transferred upon import into another module. Runtime checks of errant assignments would be relatively easy: trap this in the module setattr operation, and henceforth let module.__dict__ return a read-only dict wrapper. (Except that would break "exec E in globals()". I guess it would have to be a dict wrapper that only makes those specific keys read-only...) -- --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
