Or, you could do a hybrid. Load the objects, then do minimal parsing on
the module, adding attributes to objects you loaded to indicate their
order, and perhaps some other small things, like finding interstitial
docstrings. That seems a lot easier than trying to do *everything*
through source parsing, which starts to get really hard at some point,
and it gives you the extra information that you want.
