This was originally suggested by Guido, discussed on the stdlib-sig mailing
list, and given the OK by Guido directly to me. What this change essentially
means is that Python has taken a policy of silencing warnings that are only
of interest to developers by default. This should prevent users from seeing
warnings which are triggered by an application being run against a new
interpreter before the app developer has a chance to update their code.
Closes issue #7319. Thanks to Antoine Pitrou, Ezio Melotti, and Brian Curtin
for helping with the issue.
catch_warnings(), and clean up the API.
While expanding the test suite, a bug was found where a warning about the
'line' argument to showwarning() was not letting functions with '*args' go
without a warning.
Closes issue 3602.

bus errors or SystemError being raised. As a side effect of fixing this, a bad
DECREF that could be triggered when 'message' and 'category' were both None was
fixed.
Closes issue 3211. Thanks JP Calderone for the bug report.
'warnings' code in places where it was previously not possible (e.g., the
parser). It could also potentially lead to a speed-up in interpreter start-up
if the C version of the code (_warnings) is imported over the use of the
Python version in key places.
Closes issue #1631171.
both a subclass of Warning and a subclass of types.ClassType. The latter is no
longer true thanks to new-style exceptions.
Closes bug #1510580. Thanks to AMK for the test.
added message attribute compared to the previous version of Exception. It is
also a new-style class, making all exceptions now new-style. KeyboardInterrupt
and SystemExit inherit from BaseException directly. String exceptions now
raise DeprecationWarning.

happen in 2.3, but nobody noticed it still was getting generated (the
warning was disabled by default). OverflowWarning and
PyExc_OverflowWarning should be removed for 2.5, and left notes all over
saying so.
Add API function simplefilter() that does not create or install
regular expressions to match message or module. Extend the filters
data structure to store None as an alternative to re.compile("").
Move the _test() function to test_warnings and add some code to try
and avoid disturbing the global state of the warnings module.
This patch makes it possible to pass Warning instances as the first
argument to warnings.warn. In this case the category argument
will be ignored. The message text used will be str(warninginstance).
warn_explicit(message, category, filename, lineno, module, registry)
The regular warn() call calculates a bunch of values and calls
warn_explicit() with these.
This will be used to issue better syntax warnings.
appends to list of filters instead of inserting at the front. This
is useful to add a filter with a lower priority than -W options.
