Instead, the macros refer to a (free) variable `id'. AFAICT, with your current implementation nothing would change if you would remove the macro argument (and the `ignore' call) and simply don't use it. Typically, the backquote expression in the macro body would have ",id" instead of "id" to include the value specified by the ID argument. The compiler warning is not just noise. Michael.
