Right. I am not thinking of an auto-cast but rather give people _some_
way to cast to/from MONEY, which is what the TODO says:

* Allow MONEY to be cast to/from other numeric data types

Even when we have multiple currency designations I would think people
would need a way to cast. I am trying to anticpate how MONEY will be
used. You are right we don't have any field requests yet, but I am
expecting them.

I have added documentation on the issues of casting to/from MONEY;
patch attached and applied.
