It may be just me, but I fail - in a complete manner - to see how this syntax can offer any improvement on current if/elif chains.
I haven't been following this thread closely, so I don't know if Lucas has mentioned more than syntax, however... In other languages, the semantics of the switch statement allow the compiler to generate more efficient code. Instead of testing each branch of the if statement in succession looking for a match, you evaluate the switch expression once, then use it as an index into a jump table of some sort which points directly to the matching case label. If nothing matches, you jump to the default branch (if one was defined) or just jump over the entire switch statement (if not). Skip
