No, I propose two forms of comparison distinguished statically.
E.g. <=, >=, <, > compare wrt. homogeneous rules (incompatible types
cause exceptions); ==, !=, cmp compare wrt. heterogeneous rules
(tries to be as close to a total order among all object values as
possible - of course a user-defined comparison is able to throw,
but it shouldn't).
