The error turned out to be in PRECOMPILE-LAMBDA and
PRECOMPILE-NAMED-LAMBDA. Committed the fix in r12340 in trunk. This
will be in 0.18.

I think it would be a good idea to extend your inline-lambda-rewriter
to be able to parse/rewrite all lambda lists, not only the ones with
&rest arguments (did I see correctly that you restricted to that
case?).

Bye,
