Surely in this case one wants stdout in a separate String to stderr?
If something fails in the middle of a long operation, I want just the
error, doc!
Well yes, but maybe you also want to tally the stderr with the stdout, 
to see what was going on at the time the errors were generated (modulo 
buffering, of course).

How about two separate versions?  In which case, what should they be called?
