You could load a DXE with code. I'm looking at doing that, but might not
because:

a) it's not portable beyond DOS+Windows
I might be able to live with this.

b) Users could write evil code
Is there any way to protect one's program from an evil DXE? Like not let it
resolve *any* symbols outside itself? It could still issue interrupts,
though.

As is, I may have to do what you're doing, and Quake does. I don't know that
I'd go with lisp--I'll probably resurrect my p-code miniC compiler from
storage.
