Yep; that should work.  What if I want to create a global function?  I
assume I can use "class << SOMETHING", but I'm not sure what the
SOMETHING would be.

I'm guessing that if I put that code outside any classes then the eval
will create a global function.  I'll try that out.

Yep. I'd thought of that, but the functions are going to be created for
arbitrary classes.

If I can make this work, I'll be a very happy boy.  At the moment, I feel
like my chances are about 50-50 :-).
