25093	utils.datastructures.OrderedSet doesn't implement __len__	Keryn Knight	Sambhav Satija	"{{{
>>> 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
