I don't agree that exceptions are the way to do "things"
in general. They're the way to so *some* things. The question
is whether the thing we're talking about is one of those

But only because NotImplemented is an out-of-band condition
for operations in general. We're not talking about a general
operation here, but a very specific one that only has a couple
of possible results.
