+   File Name:          11.9.2.js
+   ECMA Section:       11.9.2 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).
