cl-defstruct accessors and predicates? I wouldn't say it's trivial, but 
it should be straightforward to implement. In Elisp, at least. In C, 
it's bound to be an order of magnitude longer.

I guess not, but that's the point: within the restrictions imposed by 
etags's design and common sense, you're not going to write an indexer 
that takes into account the many different ways Elisp can define 
functions implicitly. And there's no way to specify those with --regex 
either.
