Groovy doesn't allow you to overload comparison operators individually, and probably most JVM languages likewise. This is to retain compatibility with Java, which has `.compareTo()` instead of `isLessThan()` etc. Ruby allows you to override individual comparison operators, with a special operator `<=>` for combined comparisons. Nim lets you overload arbitrary operators and create your own; some old discussions suggest that the Comparable type is based on `<` alone.
