Great, thanks!  I don’t know if the best approach here is to add lengthy docstrings or move the information from the comments into the reST docs.  Maybe this should be asked on the core-mentorship or python-dev mailing list.

In docstrings as well as in reST docs we just use English, with asterisks to mark up parameters, e.g. “*path* is an instance of :class:`ElementPath`. ... Returns ``True`` if there is a match, ``False`` otherwise.”

Doctrings for C modules are not hard to find, just a little painful to write.  If we agree to turn comments into docstrings and you need help, I’ll be glad to guide you with that.
