Yes, I think it would be a nice addition, and I'm sure we're not alone - 
many people on the group contributed with ideas on this topic. While I 
understand that there are some issues with the proposal - including or 
excluding the upper limit, using braces to delimit the range, or how to 
specify the step operator - I believe that the concerns are mostly in the 
reaction-to-change field.

So, if we can propose a new syntax that:

- is clear for both novices and experienced Python programmers
- does not break anyone's code
- is consistent with related features (slicing and list comprehensions)

... there will be no real reason not to make it.


p.s. I was one of the guys that wrote about 'creeping featurism' a few 
months ago. I don't think that it is a good idea, and many PEPs were really 
weird. Now, this seems to be a very simple addition to me, because we can 
meet the three criteria above. I'm happy to be proved wrong, but please, 
let's talk about facts, not emotions, ok?
