Note that Ada 2020 will have a package FIFO_Streams for this purpose (that 
is, marshalling/unmarshalling streams). See AI12-0293-1 or 13.13.1 in the 
draft 16 or later RM: 
http://www.ada-auth.org/standards/2xrm/html/RM-13-13-1.html (toward the 
bottom).

We had to write such a package for Claw, in order to allow using stream 
attributes to put/get items from Windows data structures like the registry 
or clipboard. It's something that you can hardly live without, which is why 
it will be standardized.
