I was being silly, it's quite beautiful... The problem is that I want
it to allow options that it doesn't know how to parse, and allow me to
throw errors later, but most people don't want that...

We could add another function "getOptSloppy" or something that allows
this, but the problem is that my changes impact most of the system, if
in a small way.

That said, I'll work on a backward-compatible change.
