+    [...]
+    b. When the FunctionDeclaration f is evaluated, perform the following steps
+       in place of the FunctionDeclaration Evaluation algorithm provided in
+       14.1.21:
+       i. Let genv be the running execution context's VariableEnvironment.
+       ii. Let genvRec be genv's EnvironmentRecord.
+       iii. Let benv be the running execution context's LexicalEnvironment.
+       iv. Let benvRec be benv's EnvironmentRecord.
+       v. Let fobj be ! benvRec.GetBindingValue(F, false).
+       vi. Perform ? genvRec.SetMutableBinding(F, fobj, false).
+       vii. Return NormalCompletion(empty).
