      9    The following rules for IfStatement augment those in 13.6:
     10 
     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]

     20    [...]
     21    ii. If replacing the FunctionDeclaration f with a VariableStatement that
     22        has F as a BindingIdentifier would not produce any Early Errors for
     23        body, then
     24    [...]

     26    B.3.5 VariableStatements in Catch Blocks
     27 
     28    [...]
     29    - It is a Syntax Error if any element of the BoundNames of CatchParameter
     30      also occurs in the VarDeclaredNames of Block unless CatchParameter is
     31      CatchParameter:BindingIdentifier and that element is only bound by a
     32      VariableStatement, the VariableDeclarationList of a for statement, or the
     33      ForBinding of a for-in statement.
