My initial reaction to this is that you want to infer structure where
none exists, so why not make the structure explicit?  In any case,
couldn't you subclass the list type and add a pop_slice method to do
what you want?  I'm not an iterator maven, but this also seems like
something you could mix up from something in the itertools module.
