In Haskell I'll have to uniquely number the s's: let (x,s1) = foo 1 [] in let (y,s2) = bar x s1 in let (z,s3) = baz x y s2 in ...This isn't a case for non-recursive let. It is one of the rare cases where you might actually consider using a state monad.
Except when you are implementing the state monad (giggle): http://hackage.haskell.org/packages/archive/mtl/2.1/doc/html/src/Control-Monad-State-Class.html#state -- Andreas Abel <>< Du bist der geliebte Mensch.
