I once wrote an OOPS in C system (called OopsCDaisy for the fun of it.)

It was super duck typed.

Every class had every method.

If you invoke a method that wasn't defined on that class or its ancestor,
it did nothing.

Worked quite well. None of this if variable has this method invoke method,
just invoke method and have done.
