+  9. Let declaredFunctionNames be a new empty List.
+  10. For each d in varDeclarations, in reverse list order do
+      a. If d is neither a VariableDeclaration or a ForBinding, then
+         i. Assert: d is either a FunctionDeclaration or a
+            GeneratorDeclaration.
+         ii. NOTE If there are multiple FunctionDeclarations for the same name,
+             the last declaration is used.
+         iii. Let fn be the sole element of the BoundNames of d.
+         iv. If fn is not an element of declaredFunctionNames, then
+             1. Let fnDefinable be ? envRec.CanDeclareGlobalFunction(fn).
+             2. If fnDefinable is false, throw a TypeError exception.
+             3. Append fn to declaredFunctionNames.
+             4. Insert d as the first element of functionsToInitialize.

+      b. Let fo be the result of performing InstantiateFunctionObject for f
+         with argument env.

+  4. Let existingProp be ? globalObject.[[GetOwnProperty]](N).
+  5. If existingProp is undefined, return ? IsExtensible(globalObject).
