To be honest, I can't think of one.  And if the presumption is this is
just going to be a special case hack, maybe we shouldn't worry about
the general-use case.

Thinking about this some more, keeping this simple might be better way
to go.  It's not like we really want to be encouraging people to use
this interface....

What do you think?
