Owen O'Malley commented on HIVE-11504:
--------------------------------------
The goal is simplicity.
For the types that are strict super-type, there is no point in distinguishing
them. It will just make all of the users of the api add more switch statements.
So my point is the x = 1000 means exactly the same thing if x and 1000 are
longs or integers. Note that this is completely different than if x were double
or string.
