As others point out, 

sys.modules[__name__]

I find myself doing this more and more, not less, as I get further into
Python; autogenerating many similar functions, pulling constants from an
external source, stuff like that, usually very meta and every instinct
says its the right thing to do. 

Maybe we should have a __module__ attribute that is a reference to the
current module? sys.modules[__name__] is a little obtuse.
