Names with leading and trailing double underscores are reserved by 
Python, so I think it would be best to avoid using them. See 
http://docs.python.org/reference/lexical_analysis.html#reserved-classes-of-identifiers

(__version__.py is already used by Mercurial, but it is a bad example. 
Especially when some standard libraries such as pydoc already buts 
special semantics into that name.)
