One has to distinguish what counts as a simple fix and what counts as a
major reorganization. All these problems with VALUES types are solved in the
new compiler framework -- which is yet unfinished --.

Part of what I want to do for the _next_ release not the upcoming one is to
begin creating common files that are shared by both compilers, so as both to
finish the new compiler and gradually perform a transition to the new
system.

This will add a lot of new features, including better handling of VALUES
types, caching of functions, etc.

But that is not going to happen this week.
