Logical const is not supported by the language. Casting away const and 
modifying a variable is undefined. As such, the language is free to treat a 
const and immutable value type on the stack identically. There is no real 
difference. True, there's a decent chance that the compiler will generate 
slightly different code depending on what the code's doing, but it doesn't have 
to. Modifying the variable is undefined in either case. The language is _not_ 
going to do anything to try and support the modifying of a const variable.
