5 description: Existing variable binding is not modified (IfStatement with a declaration in both statement positions in eval code)

7 flags: [generated, noStrict]
9 The following rules for IfStatement augment those in 13.6:
11 IfStatement[Yield, Return]:
12 if ( Expression[In, ?Yield] ) FunctionDeclaration[?Yield] else Statement[?Yield, ?Return]
13 if ( Expression[In, ?Yield] ) Statement[?Yield, ?Return] else FunctionDeclaration[?Yield]
14 if ( Expression[In, ?Yield] ) FunctionDeclaration[?Yield] else FunctionDeclaration[?Yield]
15 if ( Expression[In, ?Yield] ) FunctionDeclaration[?Yield]
18 B.3.3.3 Changes to EvalDeclarationInstantiation
21 b. When the FunctionDeclaration f is evaluated, perform the following steps
22 in place of the FunctionDeclaration Evaluation algorithm provided in
24 i. Let genv be the running execution context's VariableEnvironment.
25 ii. Let genvRec be genv's EnvironmentRecord.
26 iii. Let benv be the running execution context's LexicalEnvironment.
27 iv. Let benvRec be benv's EnvironmentRecord.
28 v. Let fobj be ! benvRec.GetBindingValue(F, false).
29 vi. Perform ? genvRec.SetMutableBinding(F, fobj, false).
30 vii. Return NormalCompletion(empty).

37 return "outer declaration";\
42 assert.sameValue(init(), 'outer declaration');
