Personally, I'm for the iteration spec in a lot of ways.

Firstly, a .get()/.pick() that always returns the same element feels horrible. Is there anyone here who _likes_ it?

I do. Since the caller is asking for an arbitrary element, returning the same element is legitimate. It's funny how people seem to have a problem with the word "arbitrary" :)

Agreed. Arbitrary is arbitrary - for a stateless method that returns an arbitrary result, return the same value every time is fine.

And I'm -1 on any implicit iteration attaching some state to the object. If you want to iterate, there's already an obvious way to it.

Also agreed.
