It occurred to me while I was writing it that using a class
would be almost as good. But not quite, for various reasons.
First, you don't actually want a class, you want an instance
of a class; either that or wrap all the functions in
classmethod, which would be rather tedious and ugly.
Using a module avoids that problem, but you still have
to import it from somewhere instead of writing it in-line.
In both cases, you either have to access it with getattr,
or do a little dance to get a dict out of it.
All these things add up to a bit more obscurity and a
bit less economy of expression. In my suggestion I was
aiming for maximum possible clarity and lack of crud.
