No, I don't think that would work.  In particular, I want to be able
to pass a class to a unit which defines a subclass of the class.  I
don't think you can do this with something like struct type
descriptors, but I'd be happy to see an example.

By the way, Matthew's ICFP paper
(http://www.cs.utah.edu/plt/publications/macromod.pdf) doesn't cover
record inheritance, and I couldn't find anything relevant in HTUS.
Did I miss something?
