But the whole of Nevow's stan is magical. It's an abomination! A hideous
abuse of Python's __getitem__ machinery! It's lovely :).

If you really want to avoid _class (_for is another) you can do:

        attrs = {'class': paraClass}
        tag = T.p(**attrs)[...]

or even:

        tag = T.p(**{'class': paraClass})[...]

Cheers, Matt
