(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

Perhaps Alan has some comments here; added to the CCs.

Hello, Lars and Johannes.

This is true.

This is also true.

There seems to be a suggestion that if CC Mode's ( were bound to
self-insert-command, suddenly eldoc facilities would become available.
This is sadly not true.

Doing a quick grep through lisp/progmodes, it seems that those languages
which use eldoc do not have compile-time type checking.  This makes it
far easier to write the whole argument sequence of a function into the
limited space of the echo area.

The languages using eldoc seem to be in a minority - Lisp, Python, Perl,
Octave.  I do not know if the eldoc infrastructure handles languages
with compile-time type annotations.

I think that to add an eldoc facility to CC Mode would be quite a lot of
work.  Patches are welcome!
