No, but there are caveats to running endless loops at the
top level of a
module on import. engine.start() starts an infinite loop;
when this
happens during an import, the module-instantiation code
never gets a
chance to complete. To "run it as a package", the
correct syntax is:

> D:devpythonhello> python __init__.py
