That might be a bad idea, since the point of fixed-size integers is that 
they are, you know, fixed-size. :P

However, I'd like it if the following compiled:
---
import std.stdio;
void main() {
     static if(is(cent))
         writefln("cent implemented");
     else
         writefln("no cent yet");
}
---
(and gave the correct output, of course)
Then anybody who cares about this sort of thing would have a way to test 
for it.
And you could use it to define aliases (max_t & umax_t ?) for the 
largest signed and unsigned integers.
