There are two big family of switches. C-like and Pascal like. In 
Pascal you can only have cases in the switch.

See https://en.wikipedia.org/wiki/Switch_statement#Semantics

The C form doesn't prevent you to be stricter but it's all about 
self-discipline since the compiler will allow everything in there.
