B.3.3.3 Changes to EvalDeclarationInstantiation
[...]
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).
