    if match("EOF", s) = 1 then --> assuming s is sequence 

    It works, but I'd rather see the not-using-a-function (compare is NOT
    seen as a function, after all it's a standard operator in most
    languages; match IS seen as a function, in BASIC you use INSTR, in
    Pascal you use Pos, in C you use strchr, in Perl you use index,
    i.e. no language has find as an operator) version. (Btw yes I know
    lots of languages.)

    Btw it's not find...

>    return not compare(s1, s2)  -- if equal return 1, otherwise return 0.

    I'd rather use objects in the arguments
