Revert "Rename args_as to args/as, result_naked to result/is_naked to make top-level properties cleaner"

This reverts commit e65b46900a4b9fc1163e71000bc67866428db8ce. What was I
smoking? (I don't even smoke). args/as conflicts with actual args! And I'll
cancel result_naked as well, not worth the trouble.
Release v1.1.50
