the compiler can of course figure that out also for if/elif/else state- ments, by inspecting the AST. the only advantage for switch/case is user syntax...

Not quite true - you'd have to restrict the switch expression in some way, so you don't have:

if x.y == 1:
   ...
elif x.y == 2:
   ...

where the compiler doesn't know if getattr(x,'y') is really supposed to happen more than once. But I suppose you could class that as syntax.
