Nice!  That's the first time I've seen the 2-parameter version of 
iter() improve things :-)  (I've seen it once or twice before in 
the 2-param form, and wondered why it wasn't written in a clearer 
way).  Also, I was surprised to learn that the sentinel was 
available as far back as 2.2 (I knew about the 1-param version as 
far back as 2.3 when I became more serious about Python).
