This post proposes the answer to a question I've had for years, namely, how to see what a generator is doing "while the generator is doing it" :-)
A long time ago, in a thread far away (no idea where), I asked Guido this question and he was stumped. Iirc, we were both looking for the answer somewhere like in python's itertools <https://docs.python.org/3/library/itertools.html>module. But during the recent rewrite of the TokenOrderGenerator class (in leoAst.py), I suddenly saw a dirt simple answer. If I want to "capture" and "restart" a generator, just do something like this: captured_list = list(yield whatever) # or "yield from" yield from captured_list To be clear, this is for debugging only. Calling list negates most of the advantages of having a generator, but for debugging we don't care. I haven't tested this idea, but it smells like the solution. What do you think?
