Eval.lhs:146:65: error:
    • Ambiguous type variable ‘m0’ arising from a use of ‘eval'’
      prevents the constraint ‘(Foldable m0)’ from being solved.
      Relevant bindings include
        virtuals :: m0 [Char] (bound at Eval.lhs:146:40)
      Probable fix: use a type annotation to specify what ‘m0’ should be.
      These potential instances exist:
        instance Foldable ZipList -- Defined in ‘Control.Applicative’
        instance Foldable (Either a) -- Defined in ‘Data.Foldable’
        instance Foldable Dual -- Defined in ‘Data.Foldable’ 13 others 29 instances involving out-of-scope types
        (use -fprint-potential-instances to see them all)
    • In the first argument of ‘runWriterT’, namely
        ‘(eval' virtuals mkfile)’
      In a stmt of an 'mdo' block:
        (rules, RevAppend virtuals) <- runWriterT (eval' virtuals mkfile)
      In a stmt of an 'mdo' block:
