Example #1

    operr = OperationError(w_error, space.wrap("message"))
    assert operr.match(space, w_error)
    assert operr.match(space, space.w_Exception)

    # subclass of ValueError
    w_error = new_exception_class(space, 'error', space.w_ValueError)
    operr = OperationError(w_error, space.wrap("message"))
    assert operr.match(space, w_error)
    assert operr.match(space, space.w_ValueError)

    # subclass of (ValueError, TypeError)
