Cyril proposed this, so may chime in with more information, but...

Take a look at 
http://forum.world.st/Polymorphism-between-Strings-and-FileReference-tt5059220.html

The advantages are:

- provides polymorphism with FileReference
- you don't need to know whether the stream needs to be closed or not
as read/writeStreamDo: takes care of it for you.

Can  you clarify what you're asking (about "why a string is a fileReference")?

To be clear, SequencableCollection>>read/writeStreamDo: open a stream
on the receiver (typically a string) and then pass it to the supplied
block.  Nothing to do with a fileReference (apart from the
polymorphism).
