The partial ordering you refer to is a more technical or mathematical

More precisely I guess this should say, all you need for a definition of
order is to
be able to define an antisymmetric relation for any two elements x and y in
A where A is the set of elements to be ordered.

The programmer in me just wants to simplify this to defining a function. :)
