michael@0 9 ECMA Section: 11.9.3 The equals operator ( == )
michael@0 10 Description:
michael@0 11
michael@0 12 The production EqualityExpression:
michael@0 13 EqualityExpression == RelationalExpression is evaluated as follows:
michael@0 14
michael@0 15 1. Evaluate EqualityExpression.
michael@0 16 2. Call GetValue(Result(1)).
michael@0 17 3. Evaluate RelationalExpression.
michael@0 18 4. Call GetValue(Result(3)).
michael@0 19 5. Perform the comparison Result(4) == Result(2). (See section 11.9.3)
michael@0 20 6. Return Result(5).
