I'm not sure I like the idea of having things that
are illegal outside a function, because it can be a
nuisance for code refactoring.
I'd be happy if case worked at the top level, but
wasn't any faster than if-elses. That wouldn't be
so bad -- top-level code is already slower due to
global variable accesses.
Also I don't care what happens if you change the
case values of a top-level case. It's undefined
