	I'm not sure I see the value in new syntax, but I think what you 
describe here would be a useful addition to itertools.  Yes, you would 
still have to import itertools, but you could just import this one 
"convenient iterator" class and use that, which could allow for concise 
but readable code that otherwise would have to use many different 
itertools functions.  It would require some thought about what sorts of 
overloaded operators (if any) would be appropriate for various itertools 
functions, but I think it could still be a gain even if the main 
advantage was just being able to write stuff like 
"niceIterator(x)[10:20] + niceIterator(y)[20:30]".  Since it would just 
be a convenience wrapper, there need be no worries about it not working 
for particular kinds of iterables (e.g., ones that already define their 
own behavior for certain operators); you just wouldn't use it for ones 
where it masked behavior you cared about on the underlying iterable.
