EQUAL function compares same things as eql, additionally result is true under some other situations: conses are compared recursively (in both car and cdr part), string and bit-vectors are compared element-wise. Result is true if they are same, otherwise false.

(equal "moo" "moo") => T (equal "moo" "MoO") => NIL (equal #*1010101 #*1010101) = T (equal (vector 2 3 4) (vector 2 3 4)) = NIL (equal (cons 1 2) (cons 1 2)) => T (let ((x (cons 1 2))) (equal x x)) => T

(equal 'moo 'moo) => T (equal 'moo 'foo) => NIL (equal 1 1) => T (equal 1 2) => NIL (equal 1234567890123456789 1234567890123456789) => T

(equal 1.0 1) => NIL (equal 1.0 1.0) => T
