This is limited to ELisp.

This is limited to ELisp and built-in Emacs functions.

I was talking about alternatives that can be used as part of the
development environment suitable for many programming languages.  If
the user needs to switch the "find definition" facility each time she
changes her project or programming language, it's not a good
situation, and therefore such a facility cannot be considered as an
alternative to etags (and ID-utils, if we are talking about finding
references).
