B.3.3.2 Changes to GlobalDeclarationInstantiation

b. If replacing the FunctionDeclaration f with a VariableStatement that has

F as a BindingIdentifier would not produce any Early Errors for script,

B.3.5 VariableStatements in Catch Blocks

|
|
also occurs in the VarDeclaredNames of Block unless CatchParameter is

VariableStatement, the VariableDeclarationList of a for statement, or the
|
|
ForBinding of a for-in statement.
