  24     ECMA Section:       11.4.4 Prefix increment operator
  25     Description:
  26     The production UnaryExpression : ++ UnaryExpression is evaluated as
  27     follows:
  28
  29     1.  Evaluate UnaryExpression.
  30     2.  Call GetValue(Result(1)).
  31     3.  Call ToNumber(Result(2)).
  32     4.  Add the value 1 to Result(3), using the same rules as for the +
  33         operator (section 11.6.3).
  34     5.  Call PutValue(Result(1), Result(4)).
  35     6.  Return Result(4).
