Pros:
- Runtime reloadability
- Runtime composability
- More flexible
Cons:
- It's a string
Can Pegged be usefully applied to implement this?
Incidentally, it seems that although Hibernated is very nice,
there is still work to be done. Eg I would like to insert 10
million rows, and it seems like a transaction would be the best
way of doing so, but it's not yet supported. No big deal since
the schema is very simple and I can do it by hand, but it would
be nice to have at some point. (I looked at your own ORM, but
keeping it in memory won't work for me).
