I think the first thing you need to clarify is as follows:
Does each 'case' statement need to be a compile time constant?

For example, even when using 'switch' with integers, we can't do:

switch ( arg )
case 0:
case 1:
case 2:
case g_some_global_variable: ;

This code won't compile if "g_come_global_variable" isn't a
compile-time constant.

So if a 'switch' statement could work with strings, would the strings
need to be compile-time const arrays of char's?
