> Doesn't Ada have constrained number types which have similar behaviour?

Yes. Just for comparison, the behaviour of the Ada number is to throw
an exception at runtime if a number overflows its bounds. If these
checks can be eliminated statically, then they are. If an operation
will always give a runtime error then this is given as a warning at
compile time.
