It works for C as well. I was using a lot of C++ templates at that time.
And Semantic didn't display them nicely.

Well, I know that the mentioned lisps can really get this info from the
REPL. Of course, the restriction is that the code needs to be loaded.
The same applies to Jedi and mozrepl/tern, I guess. Not sure if there's
any good similar tooling for Ruby.

The thing is that function-args adds some functionality that would be
missing otherwise for C++.  Ruby and Python already have some of this
functionality by extracting it from the REPL. Of course, it would be
nice to make it work everywhere, but it's not urgent if the gap is
already filled by something else, e.g. Jedi.

That's nice. But somehow I don't see why anyone would not just use
Clojure if you need a JVM hosted language.
