Also, could this be simplified? Could Size have a Num instance? A MonoFunctor instance should definitely be possible.

Ok, turns out writing a Size instance is not all that hard once one has found the Size combinators in Data.Store.Internal.

I think these should be more prominent and possibly moved into a non-internal module, maybe something like Data.Store.Size.

A separate non-internal module makes sense to me!
