IMAO what we should have done was to have had two different sets of operators, one set of numeric comparisons (without type conversion) and one set of gerneral term comparisons (without type conversion). So for example:

Just like Erlang's predecessor Prolog!
Since the term/number distinction _was_ borrowed for equality and
inequality (although with the symbols switched around, which still
confuses me), I've often wondered why it wasn't borrowed for ordering.
