It was an example, and there are plenty of cases where you want to 
restrict your destination to be local simply because completing on a 
zillion options is slow, regardless of the tool used to create said list.

That might work in a simple case, but for current tag to truly be 
accurate, you need to parse the whole buffer from start to point so you 
don't get confused by text in strings, text in comments, nested function 
syntax, and #ifdef type syntax.  Once you do that, you might as well 
just parse the whole buffer and cache it.

Yes, there are some guidelines on what functions there are but I haven't 
tied much together into minor modes or keybindings.  We used to have 
'senator' mode which we updated with new stuff, but the Emacs merge has 
gotten that a bit confused.

As an added bonus, all the semantic-ia-* functions were originally meant 
to be examples on how to use the infrastructure for someone who wanted 
build interface functions, so they lack a bit of polish and haven't been 
promoted into keymaps.

It would be great if someone interested in the user interface side could 
help out getting the right interface together on top of some of the 
semantic concepts.
