    ECMA Section:       11.9.1 The equals operator ( == )
    Description:

    The production EqualityExpression:
    EqualityExpression ==  RelationalExpression is evaluated as follows:

    1.  Evaluate EqualityExpression.
    2.  Call GetValue(Result(1)).
    3.  Evaluate RelationalExpression.
    4.  Call GetValue(Result(3)).
    5.  Perform the comparison Result(4) == Result(2). (See section 11.9.3)
    6.  Return Result(5).
