[Openmcl-devel] traceback help

That's partly an artifact of bug 294

<http://trac.clozure.com/openmcl/ticket/294>

A function that had some sort of problem at compile-time gets defined
as a 0-argument function that signals an error at runtime.   If that
function's called with the number of arguments it would ordinarily
have expected, it complains about that.

This is wrong in many, many ways.  I didn't introduce this and don't
fully understand the issues that it was supposed to address; all that
I can say is that I hope that it's fixed soon.
