That's not true, Ruby for example has operator overloading, and has no
problems with different meanings of x>y and y<x (but i don't know a
core class that does that).

Also, PHP already breaks the transitivity rule for the equality
operator ($a =3D=3D $b and $b =3D=3D $c does not imply $a =3D=3D $c), so th=
ere's
not much new evil if a user can, by loading an extension, break the
symmetry of the comparison operators, IMO.
