description: Extension not observed when creation of variable binding would produce an early error (for-of statement) (IfStatement without an else clause in eval code)
esid: sec-functiondeclarations-in-ifstatement-statement-clauses
flags: [generated, noStrict]
info: |
The following rules for IfStatement augment those in 13.6:
IfStatement[Yield, Return]:
if ( Expression[In, ?Yield] ) FunctionDeclaration[?Yield] else Statement[?Yield, ?Return]
if ( Expression[In, ?Yield] ) Statement[?Yield, ?Return] else FunctionDeclaration[?Yield]
if ( Expression[In, ?Yield] ) FunctionDeclaration[?Yield] else FunctionDeclaration[?Yield]
if ( Expression[In, ?Yield] ) FunctionDeclaration[?Yield]

ii. If replacing the FunctionDeclaration f with a VariableStatement that
has F as a BindingIdentifier would not produce any Early Errors for
body, then
