   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).
