Mixins are a great idea. Whatever decision is made about the position and
name of the inheritance declaration, they add a lot of value and are very
easy to understand.

A couple of related ideas:

class Vector {
    <superclass: Point, uses: Comparable>

"uses" looks like a better fit. It's shorter and it's already used by many
documentation generators (YUI Doc comes to mind). Also, more than one mixin
could be easily added:

class Vector {
    <superclass: Point, uses: [Comparable, Measurable]>
