It is my understanding that under the "close_after_use" proposal, infile
will be closed by .read() in both cases.

Still, I don't like this idea.  I puts action specification (close) too far
from where the action is taken.  The two-line example already makes me
uncomfortable and imagine if infile is passed through several layers of
function calls before infile.read() is called.

I would rather see read_and_close() and write_and_close() convenience
methods for file objects:

 data = open("foo.txt").read_and_close()
