Out of topic, but you gave me the clues.
Do you know where i can read up about AST trees for javascript?
Thanks a ton,

Just curious why you need the comments in the AST at all? If you've
got the start position & length of every token in the AST (much easier
to do) you implicitly have the comments as well. The "fiber" engine in
Streamline
(https://github.com/Sage/streamlinejs/blob/master/lib/fibers/transform.js)
does this with really good results.

Well, the code generator doesn't yet have an option to keep comments,
but I can add it easily; the harder part was having them in the AST,
and that's done.
What exactly are you trying to achieve? My understanding is that you
compile Lisp to JS (cool!), do you want to be able to do the reverse
transform? If so, perhaps a better idea is to generate a source map.
(not sure what you need to do though, just guessing)
