Mainly question about specification and semantics; the code itself looks fine to me.

The collections extension doesn't seem to be mentioned in the main spec; is there a spec for it somewhere else?

Not yet, it is somewhat of a placeholder for adding more list operations. See #725

What is the behaviour of the program if the list is empty? (Panic? Error? Doesn't seem to be captured in the signature.)
