OK, but my problem is precisely the impedance mismatch between range and 
newbies -- do you really think that they come pre-equipped with an 
understanding of range and half-open intervals?  I am happy enough with 
[x]range when it comes to programs that I write for myself, but would like 
a more intuitive syntax for using in algorithms lectures where I can't 
expect the students to know Python syntax.

It sounds like too many Pythonists see this as a non-problem, so it is 
unlikely to change and I will continue using non-Python for my lectures.
