> even the manual says the result may be 'unpredictable'
It's not totally brain dead. I agree that if you don't know what you're
doing, you shouldn't use it, but it is nice where you've got a series of
columns that you're grouping on, but one of them is unique. The only way
it's "unpredictable" is if you're using it wrong. But then that's the case
with anything.
