Right. But most people don't compare complex numbers.
E.g., Fortran will only let you compare them for equality/inequality.
And since comparing floating-point numbers for equality is always
a little suspect, ...
I think <, >, et al. were a hack for points.
Makes some of the code for checking containment of points
in rectangles simpler. Not much use otherwise.
Many things besides apples and oranges can't be meaningfully compared.
