I just read the PEP340 basically the first time so bear with me. First i note that introducing a keyword 'block' would break lots of programs, among it half of PyPy. Unlike many other keywords 'block' is a pretty common variable name. For invoking blocktemplates i like the no-keyword approach, instead. However, i would find it much clearer if *defining* blocktemplates used a new keyword, like: blocktemplate opening(filename, mode="r"): ... because this immediately tells me what the purpose and semantics of the folowing definition is. The original overloading of 'def' to mean generators if the body contains a yield statement was already a matter of discussion (ASFAIK). When i came to Python it was at 2.2 and i remember wondering about this "def" oddity. Extending poor old 'def' functions now to possibly mean block templates gives me semantical overload even if it is justified from an implementation point of view. I am talking purely about (my sense of) code readability here not about implementation. cheers, holger _______________________________________________ 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
