  position
info: |
  IfStatement :

    if ( Expression ) Statement else Statement
    if ( Expression ) Statement

  - It is a Syntax Error if IsLabelledFunction(Statement) is true.

  NOTE It is only necessary to apply this rule if the extension specified in
       B.3.2 is implemented.

  In the absence of Annex B.3.2, a SyntaxError should be produced due to the
  labelled function declaration itself.
