Both CIDER and SLIME look like a good candidate among third-party

ELPA because of inf-ruby dependency; it's also begging for a rewrite...)

There is M-x xref-find-references. Neither of the two current backends 
implements it, though (but I know SLIME has such a feature, and CEDET 
probably has something comparable). We could bind it to `C-M-?.
