Reserving a common English word as a new keyword (whether fail or
impossible) is the mother of all breaking changes. The syntactic sugar it
provides is not only tiny, it's pretty much negative, since any message it
could provide would be too generic to be of much use, versus raising your
own relevant exception message.
