I tried your solution, but I think we miss the split element

eg for
 >>> e = enumerate([0,1,2,3,4,5])
 >>> for i,a in e:
... 	if a==3: break
...
 >>> for i,a in e:
... 	print i,a
...
4 4
5 5
 >>>

I think the second loop needs to start at 3 ie the split needs to be 
start, limit semantics

It would be nice to be able to fix it with a move back method.
