utils.datastructures.OrderedSet doesn't implement __len__

Description 

>>> x = set([1, 2])
>>> len(x)
2
>>> from django.utils.datastructures import OrderedSet
>>> y = OrderedSet([1, 2])
>>> len(y)
TypeError: object of type 'OrderedSet' has no len()

Given the implementation of __iter__, it seems like it would be plausible to re-use that:

>>> len([z for z in y])
2
