This is the strength of typing, right? If I can specify the type of my input I can ensure the verification.

  How so? If you specify the type int how would that save you from an overflow/underflow at runtime?

    Not sure if types are supposed to protect against overflow/underflow, it's more in the arithmetic territory. Interesting idea though, I wonder if some programming language allows overflow/underflow checks directly in the types.

      Yes, it's actually quite easy: +: (int<N>, int<N>) -> int<N+1> // or (int<N>, bit) as the return type *: (int<N>, int<N>) -> int<2*N> etc. Those are the actual types of those arithmetic operations.
