Uh, without regular expressions, a lot of functions would be massively more complicated and annoying to write. However, your example shows that pattern matching barely makes common code shorter (admittedly, on this _one_ example, but that's the one you chose ;-)). While I agree that regular expressions are far less Pythonic than the proposed variant of pattern matching, they also have a tremendously better cost/benefit ratio, IMHO.
