there's no shortage of Python constructs that are functionally identical
to existing constructs. as with all syntactic "sugar", the emphasis
should be on what the programmer wants to express, not how you can
artificially constrain the implementation to make the new thing slightly
different from what's already in there.
and the point of switch/case is to be able to say "I'm going to dispatch
on a single value" in a concise way; the rest is optimizations.
