You do hasattr(..., '_covers') somewhere. Mention this module there. 

Or even better, add another function here:

def get_coverage_path_function(func):
  return getattr(func, '_covers', None)

(maybe with less verbose name)

and use it instead of refering '_covers' directly.

Self-documenting code!..

Yep I did that

+    return func
