I think the real issue is about the syntax... because of python's unique indent strategy going back to ABC, a pythonized switch statement would play havoc with the many text parsers out there used for development (TestWrangler, and many others). Personally I would still like to see a pythonized switch statement at some point. I prefer the syntactical form of PEP 275, but unlike the notion of dropping optimization and converting to if elif else under the proverbial covers, I would prefer to see a conversion to the dict dispatch table under the covers. At any rate... and I don't think even Guido can really argue against this,... a switch statement is just more readable to human beings that a dict dispatch table, or a long if elif chain... and one of the main points of python (going all the way back to ABC) was to make very highly readable code. marcus -- https://mail.python.org/mailman/listinfo/python-list
