Same here, but it's probably just b/c its unusual --its not something you
can really do in any other language but Ruby, that I know of. Granted it is
not perfectly ideal in that modules don't "inherit" exactly in the same way
classed, but that turns out not to be much of an issue in this case. The
whole notion of this was a sort of inverted factory, so the forward facing
API looks normal, e.g. `Main.new`, but versioning still occurs under the
hood.

Yes, that's the traditional factory approach. I actually would not want to
use "MainFactory", as don't want it to be explicit. But it occurs to me
that I could have redefined `Main.new` as a factory method and done it that
way. And the more I think about it the more that seems like a better
approach. It would work well for Main as well as other classes within it.
