I'm a fairly experienced Python programmer, and I still just fire up a REPL to confirm certain uses of range() with steps. What would it be like if the string form looked like this: >>> range(1, 30, 3) range([1, 4, 7, ..., 25, 28]) In theory, this could actually be made legal, and could be a cool feature for an enhanced REPL to support. (All you have to do is define 'range' as a function that checks if it's been given a list, and if not, passes it on unchanged.) Whether this form or the original, I think this would be an improvement.
