Are you sure? For me on python2.5, it works as advertised:
from __future__ import with_statement
def test(outf):
with outf:
outf.write("test\n")
try:
outf.write("test\n")
assert False, "Not closed"
except ValueError:
pass
outf = open("/tmp/foo", "w")
test(outf)
outf = file("/tmp/bar", "w")
test(outf)
Which Python do you use?
