For example, section 3.13 ends with the note:
case x of { (a,_) | let b = not a in b :: Bool - a }

end with a type signature.
I would support changing a type signature to an expression type
signature in this note

There is no a priori reason why b should depend on a in a pair of

There is: section 3.16 says that in an expression type
