Two thoughts:

1) Don't call a class instance exec, it will mask the built-in
exec statement.

2) IMHO all the suggestions are way more complicated than
if __name__ == "__main__" and are not SOP for most pythoneers.
I know what the former construct means/does.  I have to
decipher your class to figure our what the latter does and it
doesn't really save you any code or provide a performance
enhancement.
