The problem is that sys:function-lambda-list doesn't like macros or special operators anymore. Clearly, the name suggests that it takes functions, but it used to work on non-functions before this change: http://sourceforge.net/p/ecls/ecl/ci/b1ec23bce8a385251f14b278c080e22e459cc70...

It's possible to use (ext:get-annotation operator :lambda-list nil), but it returns a string for LET (ext:get-annotation 'let :lambda-list nil) => "(let ({var | (var [init])}*) {decl}* {form}*)"

Thanks for the details. Although I don't get errors for other common macros, I noticed that documentation is not shown for macros such as PUSH or PUSHNEW as well, which this also explains.

So I today had some time to do a small test and the following function indeed seems to work better in general.

(defimplementation arglist (name) (let ((arglist (ext:get-annotation name :lambda-list nil))) (if (or (null arglist) (stringp arglist)) :not-available arglist)))

Thanks again,
