> Drill tries to do implicit cast during runtime, and we agreed that if
> particular cast is not implemented run time exception is fine for now.
> However, it feels weird to get four of them at the same time.
> I think we should throw exception on the first incompatibility and stop
> processing rest of the arguments.
