2470,read for StdGen fails for arbitrary string,guest,,"According to the docs for StdGen:

""In addition, read may be used to map an arbitrary string (not necessarily one produced by show) onto a value of type StdGen. In general, the read instance of StdGen has the following properties:

    * It guarantees to succeed on any string.
    * It guarantees to consume only a finite portion of the string.
    * Different argument strings are likely to result in different results.""
