Yeah, "fast failing" is probably the most useful effect of this. I've 
written programs that relied on proper ordering and would either 
explicitly fail or produce unexpected results at some time long into 
processing the input; if there had been an option to make my program 
fail unless you present it with sorted input, I might have used that.
