Looking at the docs for warnings.simplefilter
(http://docs.python.org/2/library/warnings.html) I think the following
script should only produce one warning at each line as any message is
matched by the simple filter
import warnings
warnings.simplefilter('default')

One quick workaround would be to use a tuple where required and then
coerce it back to Result when needed
Hi,
I was hoping namedtuples could be used as replacements for tuples in all
instances. There seem to be some differences between how tuples and namedtuples
are created. For example with a tuple I can do:
a=tuple([1,2,3])
with namedtuples I get a TypeError:
from collections import namedtuple

Hi,
I've written a decorator that prints exceptions and I'm having some

My decorator is:
