> Various improvements can be made to validating the signatures and type usages
> in DoFns. Some things that should probably be checked:
> * Check that StartBundle and FinishBundle contain any emit parameters andÂ
> side inputs present in ProcessElement
> * Check that any side inputs/emits have correctly matching types between
> Start/FinishBundle and ProcessElement
> * Check that parameters and return values for the various methods are valid
> (for ex. Teardown/Setup should have no params)
