     9    ECMA Section:       11.4.4 Prefix increment operator

    10    Description:

    11    The production UnaryExpression : ++ UnaryExpression is evaluated as

    12    follows:

    13 

    14    1.  Evaluate UnaryExpression.

    15    2.  Call GetValue(Result(1)).

    16    3.  Call ToNumber(Result(2)).

    17    4.  Add the value 1 to Result(3), using the same rules as for the +

    18    operator (section 11.6.3).

    19    5.  Call PutValue(Result(1), Result(4)).

    20    6.  Return Result(4).
