A Grep-based implementation is fairly easy to do, so not too much time 
is wasted. On the other hand, it can exercise the new APIs and provide 
the necessary feedback.

"jump to definition" is about accurately recognizing references. But if 
you're jumping to foo.bar(), and Emacs doesn't know the type of 'foo', 
at least it can show you the definitions of all methods named 'bar', and 
you'll be able to choose for yourself. Using etags-select, for instance.

That's defeatism. Doesn't it bother you that every third-party package 
uses a (sometimes subtly) different set of key bindings, and a different 
way to present the same kinds of information (definitions, references, 
documentation, etc)?
