I guess it is worth mentioning though that all integers in D 
follow the semantics of modular math, so you would not be able to 
conduct proofs with the assumption that you work with natural 
integers. So you cannot assume that "x+1 > x" for any type in D, 
that might make many proofs more difficult.

Modular math can be handled with bit-blasting (turning each bit 
to a logic expression and use SAT), but maybe with less success.
