Yeah, the very strange this is that __package__ (in that code in Importer.cs) is done BEFORE the module is even loaded. I don't see how it could be ever setting the __package__ attribute correctly. In CPython, import.c is about as "confusing" as Importer.cs, so at least IP is compatible with CPython in that respect :-)<div>

issues like this. I’d suggest looking at CPython where it sets it and then making IronPython work the same.
