Although I have never used Python 2, the idea to distinguish fixed-sized and something lazy, even for Python 4, reminds me of the transition from str-unicode to the present state of affairs, but with much higher impact.To be honest, I do not like some aspects of how Python 2 issue has been resolved (especially bytes part) but it is another topic.

Since Python 4 came up, I'd like to make something clear. Python 4 is *not* going to be a release where we break compatibility with a whole bunch of things at once. Basically if you think you'll need to wait for Python 4 to get your favorite change to the language, you can forget it. You need to come up with a plan to introduce the change without breaking existing code or at least a clear deprecation schedule.

Oh no, I was misunderstood. I think that we have already come to some consensus which syntax can be discussed. In any case, I did not want to produce unnecessary noise, I apologize.

With kind regards, -gdg
