Subject: Re: 29.0.60; compiler-macros in keymap.el accept wrong number of arguments

I guess I was wrong.  There is no problem in the compiler macros, but
`*--anon-cmacro' should not be called with `elisp--witness--lisp'.

I think this bug is equivalent to
bug#50034: 28.0.50; elisp capf error "Wrong type argument: listp,
elisp--witness--lisp"
