Hi Ludovic,

I'm almost finished making the changes -- in fact, I've got everything
fixed except for this one:

>         (and (pair? obj)
>              (eq? (car obj) exception-type)))))

The thing is, I can't throw with a key that's not a symbol.  I've been
trying to rig up something using SRFI-34-style exceptions (key =
'srfi-34, args = anything) -- provided I can make that work, would
that be okay?
