> Currently, the Python SDK supports the pattern: "['my', 'list'] | MyPTransform()", which will return the results of running MyPTransform on the given list in an "eager evaluation" of the generated pipeline.  For Python Beam runners, we also support the use of PTransformOverrides to allow runners to override the behavior of specific transforms.  If this is used to override a transform that is used in eager evaluation, the evaluation will fail, as the eager evaluator looks for the result of the original applied transform, which will have been overridden away.
