Also, if you were going to go down the route of creating
classes on the fly, you would want a factory function
to create a class suitable for the purpose at hand,
and then make instances of that class. Otherwise, you
would be creating a new class for every *instance* of
your struct, which would be extremely wasteful (type
objects are *big*!)

And if you're doing that, you might as well just have
some built-in or library class that you can subclass.
