When I do that, it just causes errors elsewhere. I couldn't find a
solution. I think there's some implicit guarantee going on here. I'd like to
identify where it is and add an assert, a cast, and/or a comment, but I don't
know the system well enough.

yeah, the problem is that `self.execution_context.delayed_applications` is a
list of `Tuple[..., SplitResultResidual]`.
and we're trying to append to that list a `Tuple[...,
Iterable[SplitResultResidual]]`. Should this be a list of `Union`, or is
something wrong here?

The number of arguments is different.

Does `create_execution_tree` return `OrderedDict[str,
operations.DoOperation]`?

I changed `BeamTransformFactory.get_input_coders` to return `Dict[str,
coders.WindowedValueCoder]`. Does that seem right?
