Upon a cursory look, after a generator 'gen' is exhausted (meaning

Only in Python 2.5 or higher though. I need to support Python 2.3 and
2.4 as well, sorry

There are two possible definition of 'exhausted': 1) will raise

Write a one-ahead iterator class, which I have posted before, that sets
.exhausted to True when next fails.

The first generator isn't finished, it yielded 1 and None. Second one
is exhausted after yielding a single value (1). The problem is that,
under Python 2.4 or 2.3 both invocations will generate the same trace
output.
This seems to be a deficiency in the trace
