I see this in the Django source code:

description = _("Comma-separated integers")
description = _("Date (without time)")

What does it do? I try it in Python 3.1.3 and it fails:

>>> foo = _("bar")
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    foo = _("bar")
NameError: name '_' is not defined

No luck in 2.4.4 either:

>>> foo = _("bar")

Traceback (most recent call last):
  File "<pyshell#1>", line 1, in -toplevel-
    foo = _("bar")
NameError: name '_' is not defined

What's going on here?
