  mhmm.. i think we need a helper function, which is malloc(size, 
count) much like calloc, the test/protections are done in the 
helper. If a slice is returned then bounds checking is 
incorporated when we cast it to something else. So i agree with 
that idea, though using malloc/calloc slice vs malloc/calloc...

  It does make me wonder if my ScaledInt will be incorporated so 
cent/ucent can be used natively (*division being the only real 
complicated and slow part of the code*). Reminds me, i gotta get 
back to the optional crypto instruction set to make it faster.
