I have reviewed these peps, and I heard Guido's 2007 keynote, as well I have heard him speak on YouTube several times about the inadvisability of a pythonized switch statement (similar to C).
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.
