+ File Name: 11.3.2.js
+ ECMA Section: 11.3.2 Postfix decrement operator
+ Description:
+
+ 11.3.2 Postfix decrement operator
+
+ The production MemberExpression : MemberExpression -- is evaluated as follows:
+ 1. Evaluate MemberExpression.
+ 2. Call GetValue(Result(1)).
+ 3. Call ToNumber(Result(2)).
+ 4. Subtract the value 1 from Result(3), using the same rules as for the -
+ operator (section 0).
+ 5. Call PutValue(Result(1), Result(4)).
+ 6. Return Result(3).
