That was the subject of PEP 204 (Range Literals) which was rejected.
I don't know why. (the stated open issues should simply all be
answered with: "no magic!").

It seems to me that it would be rather neat to extend the list
comprehension idea to be able to create an iterator rather than a
list.  I shudder at the idea of proposing syntax for that, but using
[| ... |] instead of [ ... ] might work.

Now excuse me while I run for cover... :-)
