   This seems to have broken the `RowCoder.from_type_hint`.
   
   So for `SqlTransform` with `NamedTuple` defined in the `main` module, the 
below code will fail because `schema_from_element_type` does not know how to 
handle a `str` type hint:
   
   ```
   beam.coders.registry.register_coder(NamedTupleInMain, beam.coders.RowCoder)
   coder = beam.coders.registry.get_coder(NamedTupleInMain)
   ```
   
   I'll see if I can send an amendment to it.
