Semantic support seems paramount (semantic-symref depends on it).

However, it seems to be a losing proposition: writing a grammar for Ruby 
is hard enough (there's no official grammar for the current version of 
Ruby). IIRC, there was some incomplete version of grammar for it in 
CEDET upstream, which doesn't work (at all? well? I don't remember 
exactly), and even if someone were to spend the effort on fixing it:

- It won't be included in Emacs, unless that someone wrote the grammar 
from scratch.
- It won't help with code completion, which is considered the primary 
goal of Semantic (AFAICT), because the latter lacks facilities to handle 
type inference, or types in dynamic languages in general.

Yes, thanks, I don't need to load a 12000-lines project to do that.
