In the section "relative imports" of the documentation for "import system", the use of relative imports is explained with the use of an example, however if you try the exact same thing it gives an error. This is nicely explained in https://stackoverflow.com/questions/14132789/relative-imports-for-the-billionth-time and https://www.python.org/dev/peps/pep-0395/. This has also been added as an open issue in the documentation . Is this still under consideration, then I would be happy to update the docs. Thanks
