+  Declaration of function when there is a corresponding global property that is
+  non-configurable but *not* a writable and configurable data property.

+  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.

+  6. If existingProp.[[Configurable]] is true, return true.
+  7. If IsDataDescriptor(existingProp) is true and existingProp has attribute
+     values {[[Writable]]: true, [[Enumerable]]: true}, return true.
+  8. Return false.
