Agreed. However I've *never* wanted to create a "positional args only"
parameter to an api that wasn't covered by *args. I also think that in
*general* allowing keyword args is an improvement to APIs.

May you do good and not evil
May you find forgiveness for yourself and forgive others
May you share freely, never taking more than you give.
