My policy for bare excepts is that without significant justification
they _must_ either re-raise the original exception or raise another
exception.  There are very few circumstances where I have allowed
my team to write pure bare excepts.  I haven't checked, but a warning
for violations of this rule may be a nice addition to pychecker or pylint.
