For some reasoning on the hybrid FS and sys.path approach, see #92 (comment) . Additionally, specific to your issue (which could otherwise be solved by ignoring
The real problem here, though, is that the feature is insufficiently thorough and doesn't ensure your local task module is first in the path in all situations, which leads to the scenario you described.
For example, we ran into the same thing just now here at Pycon sprints, with Invoke itself:
The good news is we just fixed this by always unconditionally putting the local task.py's containing directory first in
