GHC tries hard NOT to choose an INLINE function as a loop breaker. But if you
write

{-# INLINE f #-}

I believe what Sven was saying is not that the Foldable instance for tuples
are given "special treatment" (which is arguably an orthogonal discussion),
but rather that -XDeriveFoldable special-cases tuples, which is certainly
true.
As Edward noted, there is one possible justification for this beha
Thanks for the clarification!

Ok, thanks Gracjan!
Ben, could I ask you to pull from:
https://github.com/michalt/nofib/tree/fibon
(https://github.com/michalt/nofib.git branch `fibon`)
Or if you prefer Phab, let me know if there's some magic incantation
to make it work with this patch (`arc` currently crashes for me)
Thanks,
Mi
