Excellent - thanks for your patience.

Right, the c-lambda macro (and the internal special form ##core#c-lambda into
which "c-lambda" expands) is not available in CHICKEN code, it can only be used
in code compiled with CRUNCH. That further implies that it can not be used inside csi, as the
foreign function interface can only be used in compiled code.

It would be possible to make the macros inside the "(crunch c)" module also
available in the CHICKEN compiler, so one could at least use it in compiled
code (which would just expand things like "c-lambda" into the corresponding
"foreign-lambda" used in the CHICKEN foreign function interface). I will
give this a try, so thanks for the hint.

If you want to see into what the macros expand, you can also pass "-dump-expanded" to
the invocation of "chicken-crunch", which will dump the node tree after
macro expansion.
