I would not be able to make it today.
I am still working on the Casting proposal doc.
I have added few rules to handle cast mechanism for operators/functions etc.
Have also added a table of data type precedence to the proposal doc. Am preparing the cast compatibility matrix for now (something similar to : http://msdn.microsoft.com/en-us/library/ms187928.aspx).
Can move ahead towards discussions on the proposal once the doc comes to a good form.
Let me know your thoughts. Drop in your comments in doc & I would pick them up.
Link to doc is attached to JIRA.: https://issues.apache.org/jira/browse/DRILL-259
