[issue25699] Easier way to specify reduced globals for doctest

[John Mark Vandenberg]

John Mark Vandenberg added the comment:

pyflakes does assume doctest run with a copy of the module scope.


However when there is an __all__, the module scope as seen by other modules 'should' be only items in __all__.  If a doctest is included in documentation, it 'should' only use names that are in __all__.

In addition, pyflakes has an outstanding feature request (https://bugs.launchpad.net/pyflakes/+bug/1178807/comments/8) that doctest run as if they are an independent module, and need to import everything that they use, so that each doctest is self-contained.

pyflakes can build support for both of those needs within the package.  No worries.  If you cant see a broader need for these, please close.
