By default, the warnings module is configured to ignore
PendingDeprecationWarnings (as opposed to DeprecationWarnings).  If you
instruct it otherwise, e.g. with -Wall, it does what you expect:

bash-2.05b$ python2.3 -Wall
Python 2.3b2+ (#2, Jul  5 2003, 11:28:28) 
[GCC 3.3.1 20030626 (Debian prerelease)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> raise "foo"
__main__:1: PendingDeprecationWarning: raising a string exception is deprecated
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
foo
>>>
