(x : a) ! x -- Incorrect normalized formIn order to substitute x in place of y we need to & x by 13 in order to avoid being misinterpreted as the x8 bound by the innermost lambda. If we perform that & then we get the correct result: '(a : Type) ! (x : a) ! (x : a) ! x@1ZAs a more worked example, suppose that you were to normalize the following expression: [ (a : Type) ! (f : a ! a ! a) ! (x : a) ! (x : a) ! ((x : a) ! f x x@1) x@1'The correct normalized result would be: J (a : Type) ! (f : a ! a ! a) ! (x : a) !

Let's call this "static linking". Dhall (very intentionally) does not satisfy this stronger interpretation of referential transparency since "statically linking" an expression (i.e. permanently resolving all imports) means that the expression will no longer update if its dependencies change.`In general, either interpretation of referential transparency is not enforceable in a networked context since one can easily violate referential transparency with a custom DNS, but Dhall can still try to guard against common unintentional violations. To do this, Dhall enforces that a non-local import may not reference a local import.Local imports are defined as:A fileA URL with a host of  localhost or  127.0.0.1-All other imports are defined to be non-localdhallThe offending opaque importdhall7An import failed because of a cycle in the import graphdhallThe offending cyclic importdhallConstruct the file path corresponding to a local import.

UnionLit "Other" _ _ -> ...) $(staticDhallExpression "./Some/Type.dhall").This would create the Dhall Expr AST from the "./Some/Type.dhall" file at compile time with all imports resolved, making it easy to keep your Dhall configs and Haskell interpreters in sync.dhallConvert a Dhall type to a Haskell type that does not require any new data declarations beyond the data declarations supplied as the first argumentdhallFConvert a Dhall type to the corresponding Haskell datatype declarationdhall=Convert a Dhall type to the corresponding Haskell constructordhallGenerate a Haskell datatype declaration from a Dhall union type where each union alternative corresponds to a Haskell constructor*For example, this Template Haskell splice: @Dhall.TH.makeHaskellTypeFromUnion "T" "< A : { x : Bool } | B >" ... generates this Haskell code: $data T = A {x :: GHC.Types.Bool} | BThis is a special case of : ZmakeHaskellTypeFromUnion typeName code = makeHaskellTypes [ MultipleConstructors{..} ]dhallOGenerate a Haskell datatype declaration with one constructor from a Dhall typeThis comes in handy if you need to keep Dhall types and Haskell types in sync.
