I really think we have to remember beginners' problems here. I know noone

one, but without beginners, there will be no growth in the Haskell community.
If we did as you suggest,
then beginners would be confronted by yet another kind of incomprehensible
message--and I fear it
would be hard to report that x=e risks evaluating e many times, in a way that
would be viewed as positive
by someone still trying to understand how Haskell works at all.
Insist the warnings be available, don't require them to be in the standard
warning level?
But then beginners will, without warning, sometimes find their code
running unreasonably
slowly. That isn't, really, any better. Too many will just conclude
"Haskell is unreasonably
slow" and abandon it.
