It works, but there are two serious problems:

  1. Incorrect emacs tags file when source-line directives are used
     (ctags might be OK).

  2. Performance problems make it unusable on large programs.

The performance problems appear to be lurking behind the GHC API, and
I'm not competent to correct them, so I've asked S&S for help.  Once
that's out of the way and I can do some real testing, I'll correct the
other problems.  

If you're currently building a compiler, it's in the utils/ghctags
directory.  If not, I can put source code on the web, though I'd sort
of prefer to have the bugs fixed.

Indeed.
