   Can we send what we talked here into the mailing list so that other committers and other contributors can refer when they review?
   
   If I am not mistaken, we're going to:
   
   1. Don't add string overriden ones anymore in Scala side
   2. Support string as columns in Python and R side since the codes are short
   3. Postpone to decide if we're going to drop string as column or not later in Scala side.
   
   Am I correct? Also, please leave reasons for each item in the email. _Please_ don't leave controversial reasons like Python's duck typing reason. IMHO It's orthogonal - semantic similarity isn't duck-typing.
