New submission from Jean-Paul Calderone <[EMAIL PROTECTED]>:
This example shows the behavior:
from warnings import catch_warnings
def test():
with catch_warnings(True) as w:
assert str(w.message) == "foo", "%r != %r" % (w.message, "foo")
test()
This fails with an IndexError from the `w.message`. That's a bit
surprising, and since this is mostly an API useful for testing, it'd be
much better if it had a well-defined, documented (ie, stable and likely
to continue working in the next release of Python) error mode.
