A function to produce list from range

would not work very well for huge ranges.
No, you need real iterators for that. Too bad for TCL.

So?

In the kinds of problem spaces that scripting languages are usually used for, wasting memory like that is just fine. When you get to a problem where the simple wasteful approach doesn't work, then you start to worry about it.

Though I admit that the better scripting languages have been moving for a while towards making it possible to replace basic data structures with real iterators. (With varying levels of ease.)

Cheers,
Ben
