Classes will not auto instantiate.

If your intention is to be able to create an instance of A per
request, use something like:

  class Instance:

    def __init__(self, type, **kwargs):
        self.__type = type
        self.__kwargs = kwargs

    def __call__(self, **args):
        assert(type(self.__type) in [types.ClassType, types.TypeType])
        return self.__type(**self.__kwargs)(**args)

    class A:
        def __call__(self, req):
            req.write('hello'+%s)%name

    go = Instance(A)

URL would then be:

   http://localhost/my.py/go?name=joe

If the class has a constructor, use keyword arguments to Instance() to
pass any arguments:

    class A:
        def __init__(self, arg1, arg2):
            ...
        def __call__(self, req):
            req.write('hello'+%s)%name

    go = Instance(A, arg1='value', arg2='value')

This presumes you are using publisher.
