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.
