See my last posting: it is srfi-18 compliant.

However half way of my experiments, I tried to (raise 1) and got to
catch some condition object.  So I read the source and found
##sys#current-exception-handler initially set something, which would
convert non-condition objects to condition-objects.  That's ok by
itself.  The problem is, that, other than via "with-exception-handler"
I've been/still am unable to modify the systems exception handler.  The
latter was what I was trying to do (similar to the SRFI-34 egg).
