filter() doesn't accept other PyQuery objects.

[username27]

Consider the following:
jsfiddle

code:

a = $("div")
b = $('[page="2"]')
a.filter(b).css("color", "red")

As you can see, filter accepts another jquery object.

PyQuery however throws the following exception:

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

    580                     if len(args) == 1:
--> 581                         selector.__globals__['this'] = this
    582                     if callback(selector, i, this):

AttributeError: 'PyQuery' object has no attribute '__globals__'

During handling of the above exception, another exception occurred:
