*some notes on equality:
eq    -"object identity" two objects are EQ if they are identical
      -however, regarding numbers and characters, this is dependent
        -upon the implementation: (eq 3 3) can legally be true or false

eql     -behaves like eq, but guarantees two objects of the same class
        -representing the same numeric or character value are eql
        -so (eql 1 1) is true, but (eql 1 1.0) is not

equal   -considers lists with the same structure and contents equivalent
        -considers strings equivalent if they have the same characters
        -looser definition of equivalence for bit vectors and pathnames
        -than eql

equalp  -(equalp "hello" "hElLo") is true
        -(equalp 1 1.0) is true
        -some other data structures also have looser equivalence
