When enumerating all possible modules, the help system tries to import 
test.bad_coding.py :-(
I tried to catch this LookupError, but then it fail on test.badsyntax_pep3120.py, 
with a SyntaxError
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python30\lib\site.py", line 427, in __call__

[Note: I don't like the (null) as a filename...]
