New submission from Brett Cannon:
Much like ImportError now has 'name' and 'path', AttributeError should get an
'attr' attribute that can only be set through a keyword argument or after
creating an instance. That would make the common ``try/except AttributeError``
uses much more robust by not accidentally swallowing an AttributeError that has
nothing to do with the attribute in question::
try:
cls.meth()
except AttributeError as exc:
if exc.attr != 'meth':
raise
