[stdlib] Adjust precedence of '->' operator
[stdlib] Adjust precedence of '->' operator

Precedence of '->' was too low.
`_ = () -> Int` was folded as:
  (arrow
    (assign
      (discard_assignment_expr)
      (tuple_expr))
    (unresolved_declref))
It should be:
  (assign
    (discard_assignment_expr)
    (arrow
      (tuple_expr)
      (unresolved_declref)))
