IMO, in Python/Pyrex switch statements never should fall through, because
it's breaks block behavior of Python, and using fall through in C-programs
is bad practice.

I'm thinking about C integer (from [unsigned] char to long) variable in switch,
and therefore cases also should be integer.

I like the PEP-3103. It's almost what I need.
