I would like to check that a char (unknown at compile time) matches a particular type but I would like to do so without if statements or a hash map as I would like it to be as fast as possible.

Ideally I would choose something like this:

enum typeIndex{
byte = 0,
ubyte,
short,
ushort,
int,
uint
}

char[6] typechars="cCsSiI";

bool check(T)(char c){
   return typechars[typeIndex(typeof(T))]==c;
}

Though I know this is implementation is not remotely correct D.
