We should be following standard Order of Operations here.  As such, the
option of no associativity should be included.  Furthermore, there needs to
be a voting option regarding how to deal with even exponents of negative
bases; i.e. treat "-3 ^ 2" as "-3 ^ 2 == 9" or as "-(3 ^ 2) == -9".

Without those options, my vote would be a firm No.
