I have a program that calculates the number of N length sequences whose sum 
is less than M. M and N are consts so it has no inputs. Runtime speed is 
of no more importance than compile time speed because I only need to run 
it once for each time I compile it. I'd rather let the CPU do the crunching 
rather than the DMD. It takes about 15min to run as is, so that would be 
about 1500+ min under DMD.
