Mike Bayer:

a lot of time is wasted here duck typing the object's current collection, when this is a fixed value.   this is run on every list assignment so this should be fixed up.   there is also the notion that if the target collection falls under the category of list or set, the incoming object would be checked only that it is an iterable, that is #3456, however that is a more controversial change.
