Thank you for your suggestion. I was thinking for a long time about 
these, and still I'm not convinced (by myself :-)) to use these 
projects. The little pecularities of these I think would make the effort 
as hard as creating a new one. Sisc's implementation was extremely 
complicated for my simple mind, so I'm using JScheme for some ideas.
Also I wanted to learn by doing - I think this argument in itself is 
enough :-)

Cheers,

Bert
