Any-type operations

What?

Order allows you to define comparison functions quickly for your custom types. Look at the Order module first to see how this works.

Enum builds on Order with some additional useful functions for custom types that have a finite number of variants.

Arithmetic lets you define arithmetic operations for your custom types. (I'm less convinced that this one is actually useful).

Why?

Sometimes you define a custom type, and you really want it to be comparable so that you can use comparison operators like < or >=. But it isn't. So you can't.

Or you want to perform some kind of mathematical calculations with your types using arithmetic operators like + or *. But they aren't numbers. So you can't.

This package provides a cheap way to define a bunch of functions that allow you to treat custom types almost like comparable or number types.

Are these like... typeclasses?

I don't think so ¯\_(ツ)_/¯

Hopefully, they are still useful though.
