You mean examples of usage?  That should be doable.  Any suggestions?

The package cries for that generalization, but I don't know how to do it
in a reasonable and efficient way.

For Elisp, I can just call `read' to get a suitable syntax tree.  For
other languages, I would also need something like an abstract syntax

Prior versions of semantic could generate ASTs, but they dismissed it
because it was too slow.  AFAIK I can maximally get something like a
flat tag list from semantic.  That's not enough to expand the thing to
other languages in a reasonable way.

But if someone has an enlightening idea...
