Oh, right. Sorry.

Robe already supports eldoc-mode. If idle-summary-mode has some UI 
advantages, I believe they should be folded into eldoc-mode as well.

COGRE sounds good, but I imagine it'll need more support than just 
dumping the AST.

And I can't get it to do anything (here's the documentation for 
automatic generation: 
http://www.randomsample.de/cedetdocs/cogre/Semantic-Support.html#Semantic-Support, 
and trying to interact with the editor manually leads to "eieio-oref: 
eieio-oref called on a class: cogre-class", etc).

It's also not in Emacs, for some reason.

I've taken a look, and it works okay as an alternative to IMenu, but 
jumping to method at point doesn't work (shows an error).

The tooling needs to be smart enough, of course.

Java IDEs support workflows like that, and I think they're more 
important than speedbar or showing breadcrumbs (*).

Just to let you know where my priorities are. Here's the current plan 
for that feature, by the way: 
https://github.com/nonsequitur/inf-ruby/issues/76#issuecomment-150182991

(*) Other things that the users ask for is fuzzy completion, showing 
completions right away after dot (Robe isn't fast enough for that) and 
working over TRAMP inside a Vagrant environment. It doesn't seem like 
CEDET integration will help with any of those.
