capturing output in memory

For the purpose of writing unit tests for code that writes to a stream  
I want to use something other than a FileStream that will allow me to  
write to it just like FileStream, but will just hold the data in  
memory. When I'm finished writing, I want to retrieve everything I've  
written as a single String. Is there a class that does that?

myStream = WriteStream new.
" use myStream as if it were a FileStream "
myString := myStream contents.

That's the nice part about the various protocol families.  It mostly just
works.

Sorry.  (WriteStream on: '')
