Indeed, it was the one I used for my stpy.py "testbed" earlier this year
(this had code that trivially found docstrings for a module and its
classes and functions/methods, and presented them (albeit not very
prettily) in HTML as such. The code to use compiler was *very* simple,
at this level.

It even works under 1.5.2 (with, I think, two lines commented out). As I
remember, it wasn't terribly fast, but who cares...

It also lacked documentation, but that just means some more staring at
code (and maybe the parser documentation) to work out what to expect.

Hmm - for the purposes we're after, any "query" is purely theoretical, I
think (i.e., in the sense that *everything* done on a datastructure
might be considered a query). At least for the moment.
