I think this is suboptimal, having to guess where modules are located, you end up with this in every module: try: import cjson as json except ImportError: try: import simplejson as json except ImportError: import json as json Perhaps the versioned import stuff could be implemented (whatever the syntax may be), in order that something like this can be done instead: import regex('__preview__') import regex('3.4') Where clearly the __preview__ version makes no guarantees about interface or implementation whatsoever. etc. _______________________________________________ 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
