      > The import resolution for namespace packages was wrong
      > Add a way to use the interpreter environment for tests
      > MergedExecutedParams -> DynamicExecutedParams
      > Fix a recursion error, fixes #1173

      > Add a repr for AnonymousArguments

      > Some minor flake8 fixes
      > Script.__repr__: include environment
      > Add params to CallSignature.__repr__

      > Improve Environment
      > Add max line length 100 to the config for flake8
      > tests: use monkeypatch.setenv
      > Don't test Python 3.3 on appveyor anymore, it's getting really hard to get all the right dependencies for it, because 3.3 is deprecated everywhere.
      > Mention that it's ok to have a line length of 100 characters in our files.

      > Directly load modules if possible, with this it's not necessary anymore to use dotted_from_fs_path, also fixes #1013.

      > Don't follow builtin imports anymore by default when follow_imports is on (goto)

      > additional_module_paths in usages never actually worked
