> It would be nice if DataFrame.withColumn could take metadata.  Currently (as 
> far as I can tell), the best way to specify it is:
> {code}
> dataset.withColumn(columnName, newCol.as(columnName, myMetadata))
> {code}
> where "newCol" is a new column (in my use case, a column created by a UDF).
> This is weird since the columnName is specified twice.
