Hello,

Consider the following recipe:

1. emacs -Q
2. type (define-advice org-capture
3. Observe "define-advice: (SYMBOL (*HOW* LAMBDA-LIST &optional NAME DEPTH) &rest BODY)

4. type (
5. Nothing appears in the echo area

Expected:
"define-advice: (SYMBOL (*HOW* LAMBDA-LIST &optional NAME DEPTH) &rest BODY)
still appears in the echo area.

May be the same problem as reported in the still unsolved bug#8432.

Thierry and João, could you please look into this?

I'm reasonably sure the source of this bug isn't in ElDoc per se,
but in elisp-mode.el's use of eldoc.el facilities, which are sometimes
very verbose due to longstanding issues.  But I will have a look.
I'd also like elisp-mode to start highlighting nested macro arguments
and keyword arguments, for example.

Yes, probably, we have the same problem with (dolist (...
Slime handles this correctly IIRC, it has a nice library handling
signatures but I don't remember the details.

Yes, you recall correctly.  Like SLY, Slime's fork, it has some
minimal sexp parsing logic that it makes use of in slime-autodoc.el.
I'll see what I can do (if you don't beat me to it), but this is
probably a very old bug: I don't remember Elisp ever handling
this correctly.
