| [...] |
| 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). |
