    14.1.2 Static Semantics: Early Errors

    StrictFormalParameters : FormalParameters

    - It is a Syntax Error if BoundNames of FormalParameters contains any
      duplicate elements.

    FormalParameters : FormalParameterList

    - It is a Syntax Error if IsSimpleParameterList of FormalParameterList is
      false and BoundNames of FormalParameterList contains any duplicate
      elements.
