Is there a way to achieve this while compiling with -betterC? I 
use a custom string struct right now, and your version needs 
TypeInfo, concatening using ~ needs the garbage collector. I have 
the feeling D is really not agreeing with the way I want to do 
things. If this is not possible, I will just roll with the Adam's 
struct solution.
