An etags generator (written in Elisp) is part of current snapshot of
the Emacs subdirectory. It is exactly as precise/correct as the imenu
generator :-) If you want to see it and can't wait for next release,
write me.

No. Sorry, but I don't want to be forced to use classes. I want to
be able to use Ocaml as a "better ML" only. This also applies to
Markus' proposal about the standard library.

I haven't thought of this really hard, but I bet there is already a
way to do that. If there isn't, I would think hard again to find a
cleaner, more functional (less stateful) way to do it. If the current
condition is kept in a global as in flex, that just drops again the
reentrancy that Christian has been working so hard to achieve.

Yes, I like this one.
