onestly, I just don't like the sentinel approach... while not perfect I 
prefer the explicit check on the throws of the StopIteration of the next 
function


    iterable = iter(some_function())
    try:
        e = iter(iterable)
    except StopIteration:
        # empty
    else:
        # stuff with e
        for e in iterable:
            # stuff with e
