You didn't read far enough.  The one I mentioned above is item
number 8 in the results from Google.  In it, Sean Ross had asked
about "for i in 0...10" and David Eppstein replies and points
out the key problem with it.

Yes, exactly the problem he pointed out.  He goes on to say
"If that's all the loop syntax can do, why not just keep the
current "for i in range(10):" syntax?
"Explicit is better than implicit."

And I agree with him.  Don't introduce extra syntax for trivial
gain...
