This is better than making it a static/class method on file (which has
the problem that it might return something that's not a file at all --
file is a particular stream implementation, there may be others) but I
don't like the tight coupling it creates between a data type and an
I/O library. I still think that having global (i.e. built-in) factory
functions for creating various stream types makes the most sense.
