I was actually thinking about this, recently. I've discovered that I primarily use overload to overload numify, stringify, and boolify in order to have objects that behave as expected when used in other situations. For example, a Null object.

I tend to avoid overloading the mathematical operators because the behavior tends to not be well-thought out when it comes to two different unrelated overloaded classes that should both behave as standard numbers.
My criteria for good software:
- Does it work?
- Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
