I raised this issue a few months ago.  It turns out that the only way of 
closing a stream at the end of serialisation is to leave the scope in 
which the stream was opened.  The reason for this is, I believe, so that 
a "footer" can be written to the stream indicating the end of the file.

It would be handy, as Seweryn suggests, if there could be a close() 
function available to users that did this, so that users could close the 
stream when they needed to.  One application of this is allowing a 
stream to be used for writing and then reading within the same scope.  
At the moment, a new scope is required to do this.
