    Int=

    Test equality of two integers

    (int= x y) is logically equivalent to (equal x y).

    Unlike equal, int= requires its arguments to be integers (or else causes a guard violation; see guard). Int= is intended to execute more efficiently on integers than equal or =, though this may not be true for all host Lisps.

    Macro: int=

    (defmacro int= (i j)
      (list 'eql
            (if (integerp i)
                i
              (list 'the 'integer i))
            (if (integerp j)
                j
              (list 'the 'integer j))))
