don't have K&R handy, but I'm pretty sure they put switch and case at
the same level (just like if/else), thus eliminating the need for silly
special suites.

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...
