Hi all,

What is the recommended way to write type hints for a tagged output DoFn
where the outputs to different tags have different types?

I tried using a Union to describe each of the possible output types, but
that resulted in mismatched coder errors where only the last entry in the
Union was used as the assumed type.  Is there a way to associate a type
hint to a tag or something like that?

Thanks,
Evan
