[New-bugs-announce] [issue21200] pkgutil.get_loader() fails on "__main__"

[Eric Snow]

New submission from Eric Snow:

Prior to 3.4, pkgutil.get_loader('__main__') would return None.  Now it results in an ImportError.  That's because it calls importlib.util.find_spec() which fails if an existing module does not have __spec__ or it is None.
