Dear developers, I apologize for asking this question, since I just found out that it has already been addressed last year:
http://common-lisp.net/pipermail/cffi-devel/2006-February/000525.html "Re: unnamed callback (closures?) [...] If all else failed, you could resort to passing something like: #+sbcl (alien-sap (alien-lambda ...)) #+ecl #| whatever is appropriate for an ecl anon callback |# as a pointer to a CFFI function." I'm a little bit worried because alien-lambda is undocumented in both the SBCL and the CMUCL manuals.
