--- Comment #6 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Adding even more output doesn't necessarily make it easier to see the problem.

It also wouldn't always be correct: maybe the overload that was found *is* the
intended one, and there really is a problem with it. Saying "Did you mean ..."
for some other overload that happens to compile without errors might not help.

If you are serious about the proposal I suggest re-opening this and changing
the subject and Severity (to "enhancement") or opening a new bug, providing
simple examples and very clear descriptions of what you'd like the diagnostics
to produce. Nobody is going to implement a feature request buried in a a bug
already closed as INVALID.
