Declaring types of identifiers is not enough, because it can't express the wish to ignore any fixnum overflow and assume that the result will fit in a fixnum.
Common Lisp get around this by allowing one to specify the range as part of the type. Specifying the range of a flonum can also help with type inferences of things like sqrt.
