(x : a) ! ((y : a) ! (x : a) ! y) xIf you were to substitute y with x^ without shifting any variable indices, then you would get the following incorrect result: C(a : Type) ! (x : a) ! (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) ! (x : a) ! f x@1 xuThe above example illustrates how we need to both increase and decrease variable indices as part of substitution:+We need to increase the index of the outer x@1 to x@2 before we substitute it into the body of the innermost lambda expression in order to avoid variable capture. This substitution changes the body of the lambda expression to  (f x@2 x@1)UWe then remove the innermost lambda and therefore decrease the indices of both xs in  (f x@2 x@1) to  (f x@1 x)) in order to reflect that one less x( variable is now bound within that scope Formally, (shift d (V x n) e) modifies the expression e by adding d+ to the indices of all variables named x$ whose indices are greater than (n + m), where mH is the number of bound variables of the same name within that scope In practice, d is always 1 or -1 because we either:increment variables by 1. to avoid variable capture during substitutiondecrement variables by 1) when deleting lambdas after substitutionn starts off at 0 when substitution begins and increments every time we descend into a lambda or let expression that binds a variable of the same name in order to avoid shifting the bound variables by mistake.dhall;Substitute all occurrences of a variable with an expression subst x C B ~ B[x := C]dhall=-normalize an expression by renaming all bound variables to "_"4 and using De Bruijn indices to distinguish them\alphaNormalize (Lam "a" (Const Type) (Lam "b" (Const Type) (Lam "x" "a" (Lam "y" "b" "x"))))oLam "_" (Const Type) (Lam "_" (Const Type) (Lam "_" (Var (V "_" 1)) (Lam "_" (Var (V "_" 1)) (Var (V "_" 1)))))/-normalization does not affect free variables:alphaNormalize "x" Var (V "x" 0)dhallBReduce an expression to its normal form, performing beta reduction does not type-check the expression.

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.
