Jim, I've been intrigued by this idea for all the years you've been
suggesting it <wink>, but I've never understood what it is you're proposing!
This is the Python-Dev list, so feel encouraged to present it in concrete
implementation terms instead of ambiguous English. Or maybe an interface?
interface a_kind_of_dictionary_that_is_a_collection_of_\
association_objects:
# ??? beats me ...
Or maybe as a C struct? For example, is "an association object" a (char*,
PyObject*) pair?
Does this kind of dictionary have keys? If so, of what type? What type are
the values? Best I can make sense of the above, the values are "association
objects", each of which contains a name and a value, and a key is maybe a
duplicate of the name in the association object to which it maps. "A name"
may or may not be a string -- I can't tell. Or maybe by "dictionary" you
didn't intend Python's current meaning for that word at all. I assume "a
value" is a PyObject*. The whole thrust *appears* to be to get names to map
to a PyObject** instead of PyObject*, but if that's the ticket I don't know
what association objeects have to do with it.

Where does the idea that 'spam' is a *module* here come from? It doesn't
make sense to me, and I'm so lost I'll spare everyone my further confusions
<wink>.
