Cool. But I guess we could just say I was thinking of 
'semantic-idle-summary-idle-function, and not semantic-idle-summary-mode 
itself.

The formatting options depend on using some rich structure like Semantic 
tags. So it would make sense to port that only after we standardize on 
some tag format universally across Emacs (are Semantic tags optimal? I 
don't know).

I only get a "Class:" prompt, without a default value or completions. 
Typing "cogre-element-peer" gives me "Could not find class ...", even 
though cogre is obviously loaded. That's in Emacs 24.5.

People working on said features should be encouraged, of course. 
Unfortunately, the two more interesting projects that I've seen utilize 
CEDET are language-specific:

- SRefactor only does anything useful for C/C++.
- Oleh Krehel's function-args even mentions C/C++ in its summary.

Perhaps, if there were more broadly applicable examples, it would lead 
to broader adoption. Maybe we should wonder why prefer making tools for 
CEDET that only target C and C++.
