Todd Gamblin 2e3303abd0 bugfix: nested directives were broken in python 3 ... - The nested directive implementation was broken for python 3 - directive results were not properly removed from the directive list when it was processed in the DirectiveMeta metaclass. - the issue was that remove_directives only descended into a list or tuple, but in Python3, the initial value passed to the function is a view of dictionary values. - make it a list to fix things, and add a regression test.		2018-12-30 00:19:08 -08:00
