My example shows multiple definitions of the same key taken from a TAGS
file, which proves that you can store there multiple values for the same
key and solve a real problem.

For references, TAGS is of little help. Grep is probably better.
Obviously, pointing to a data member or function and asking for the
references to *that* data member or function is something that is beyond
what Emacs core will provide on a realistic timeframe. People interested
on adding that feature to Emacs core would be more productive directing
their effort to GCC than to Emacs.
