When somone demonstrates an infinite WHILE-loop, then I will very happily concede that an "infinite" FOR-loop is not currently possible. Because apparently an infinite WHILE-loop is "trivial", I look forward to this demonstration soon... (although I fear that I might not survive the heat death of the universe to view preliminary results).
I'm also leaning towards false, since even if the number of iterations is functionally infinite (and 9,223,372,036,854,775,806 is), I can only think of ways that result in a finite number of iterations.
