Hey thanks! Still I'd welcome if you at least look over my changes and
give me some hints if you see room for improvements - most of what I did
in scheme in the past was in scsh ;)
As I said in my previous mail, I'd like to know if there is a better way
to handle the null pinter problem reported by Dave, e.g. does guile have
a null-pointer? or something comparable more gentle on the eyes than (eq
%null-pointer ..)? If not, would it make sens to add such a predicate?
Thanks
Detlev

Once the implementation is up and running, it is still a trick to keep it
running. In a normal, closed implementation, this is not a problem; in a
system with metaobject protocols [..] there is the potential for spectacular
failure modes if certain situations are not properly anticipated.
