That would be a separate proposal (PEP 288 or PEP 325). The do/with statement with its __enter__ and __exit__ APIs is entirely independent from generators. Having shown a few non-generator do/with wrappers I'm not so sure there's a lot of need for generators here; especially since generators will always have that round-peg-square-hole feeling when they're used in a non-looping context. But I still want to leave the door open for using generators as do/with-templates, hence my modification of PEP 310 (otherwise we could just accept PEP 310 as is and be done with it). For coroutines, see PEP 342. -- --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
