Only providing modular arithmetics is a significant language

modular then there is no fundamental semantic difference either.
`ulong.max` and `-1L` are fundamentally different semantically,
even with two's complement modular arithmetic.
Just because a few operations (addition and subtraction, mainly)
can use a common implementation for both, does not change that.
Division, for example, cannot be done correctly without knowing
whether the inputs are signed or not.
