That looks great. I want to suggest renaming a few functions to make 
them more consistant and (hopefully) more expressive, as I see I'm not 
the only one frowning on them.

So right now you're defining this:

r.getNext
r.putNext

r.left
r.next
rightUnion(r, s)
rightDiff(r, s)

r.right
r.pop
leftUnion(r, s)
leftDiff(r, s)

Here's my alternate naming proposal:

r.headNext
r.putNext

r.head
r.next
r.nextUntil(s)
r.nextAfter(s)

r.rear
r.pull
r.pullUntil(s)
r.pullAfter(s)

Note that r.headNext is literally r.head followed by r.next when you 
have a forward iterator.  You could also add "rearPull" to 
bidirectional ranges if you wanted. :-)

The syntax is a little different for binary functions (union, diff) as 
I changed them to members to make things easier to read and more in 
line with the regular next and pull.
