<interactive>:3:19:
    Found hole ‘_’ with type: t1
    Where: ‘t1’ is a rigid type variable bound by
                the inferred type of b :: t1 at <interactive>:3:15
    Relevant bindings include
      b :: t1 (bound at <interactive>:3:15)
      it :: t (bound at <interactive>:3:1)
    In the expression: _
    In an equation for ‘b’: b = _
    In the expression:
      let
        a = True
        b = _
      in undefined

Somehow a is not there, even though b itself is.

Tested with 7.8.3 and 7.10.1
