  24     ECMA Section:       11.13.2 Compound Assignment: %=
  25     Description:
  26
  27     *= /= %= += -= <<= >>= >>>= &= ^= |=
  28
  29     11.13.2 Compound assignment ( op= )
  30
  31     The production AssignmentExpression :
  32     LeftHandSideExpression @ = AssignmentExpression, where @ represents one of
  33     the operators indicated above, is evaluated as follows:
  34
  35     1.  Evaluate LeftHandSideExpression.
  36     2.  Call GetValue(Result(1)).
  37     3.  Evaluate AssignmentExpression.
  38     4.  Call GetValue(Result(3)).
  39     5.  Apply operator @ to Result(2) and Result(4).
  40     6.  Call PutValue(Result(1), Result(5)).
  41     7.  Return Result(5).
