This fits under the above, rule #1, of not needing additional files.
Most notably, this rules out zlib.pyd, _bsddb.pyd,

I would not consider those as being part of "simple" programs. But
that's only an opinion and we need something more objective than opinion.
Now that I think of it.. Rule 2 above should be...
2. "The minimum (modules) required to run an agreed upon set of
"common simple" programs.
Frequency of use is also an important consideration.
Maybe there's a way to classify a programs complexity based on a set of
attributes.
So... program simplicity could consider:
1. Complete program is a single .py file.
2. Not larger than 'n' lines. (some reasonable limit)
3. Limited number of import statements.
(less than 'n' modules imported)
4. Uses only stdio and/or basic file operations for input
and output. (runs in interactive console or command line.)
Then ranking the frequency of imported modules from this set of programs
could give a good hint as to what might be included and those less
frequently used that may be excluded.
Setting a pythonxx.dll minimum file size goal could further help. For
example if excluding modules result is less than the minimum goal, then
a few extra more frequently used modules could be included as a bonus.
This is obviously a "practical beats purity" exercise. ;-)

Ron
