  Sphinx doesn't like the reify decorator
  > Failed to get a method signature for kinto.core.resource.Resource.timestamp: <pyramid.decorator.reify object at 0x7f175ae45640> is not a callable object
  
  If I understand correctly this is because the reify decorator doesn't pass along the function signature.
