This was more in the way of returning the type that was given: if you start with a list you end up with a list in "b", if you start with an iterator you end up with an iterator.

I don't think that returning the type given is a goal that should be attempted, because it can only ever work for a fixed set of known types. Given an arbitrary sequence type, there is no way of knowing how to create a new instance of it with specified contents.
