7960 :: Can I create a string stream from its own data?

  I need to iterate over the content of a StringStream twice. Because StringStream does not provide a seek method, I thought instead to create a new StringStream from the first stream's data attribute and assigning it to the same variable.

  strm = newStringStream(...)

  Iterate through strm...

  strm = newStringStream(strm.data)

  Iterate again through strm...

  This works in my tests and looks to me reasonably elegant, but is this safe for all stream sizes?

  Well firstly you can just setPosition(0) to iterator over it, secondly there are a multiude of peek operations which do not move the position of the stream.

  Cool! setPosition it is! Much better! Thanks! (I just searched for "seek" and couldn't find anything...)
