Actually, I find myself sometimes doing this:

class View(object):

    def foo(self, x, y)
        return x+y

    def bar(self, a, b):
        return x*y

<browser:page
    name="foo"
    class="View"
    attribute="foo"
    />

<browser:page
    name="bar"
    class="View"
    attribute="bar"
    />

It's a convenience thing but it pops up here and there.
