Given Octave's current parse tree based interpreter, it might be a
little bit tricky.  I have some ideas about converting the parse tree
to a byte-code stack for improving performance, and I think that would
also make debugging a bit easier.  But again, it takes considerably
longer to implement these ideas than it does to come up with them, so
I don't have any idea when (or if) I will get a chance to actually
work on this project.

It would probably make things a bit easier.  :-)
