Very clever... you have shown that current python syntax is capable of
almost exactly replicating a C case statement.

My only problem is C case statements are ugly. A simple if/elif/else is
much more understandable to me. 

The main benefit in C of case statements is the compiler can optimise
them. This copy of a C case statement will be slower than an
if/elif/else, and just as ugly :-)
