Yes. > By "macros", do you mean cl-flet and cl-labels here (as opposed to > function)? I'm talking about any call to an identifier that is "currently" defined as a macro. This can be either because the `symbol-function` holds something of the form `(macro . )` or because `macroexpand-all-environment` has an entry for that identifier. > What do you mean by "hard-coded cases"? The face that `macroexp--expand-all` handles the `function` identifier as follows: (pcase form [...] (`(,(or 'function 'quote) . ,_) form) [...] -- Stefan
