RegexURLResolver can get urlpatters list defined by set_urlconf, but get_resolver returns TypeError

[anonymous]

Example from tests:

from django.core.urlresolvers import set_urlconf, reverse
from django.conf.urls.defaults import *

urlpatterns = patterns('',
    url(r'^router/$', router, name='router'),
    url(r'^router/api/$', router.api, name='api'),    
)

class TestRpc(TestCase):
    
    def setUp(self):
        set_urlconf(urlpatterns)
    
    def tearDown(self):
        set_urlconf(None)
    
    def test_base(self):
        print reverse('router')

Problem is that *patterns* returns *list*, which can't be key of cache in *memoize* function, which wraps *get_resolver*. So simple:

urlpatterns = tuple(urlpatterns)

resolves this problem for my example.

I may be missing something, but why not use the urls option ("​https://docs.djangoproject.com/en/dev/topics/testing/#urlconf-configuration) if you want to swap that out in a test case.
