Simple example: from __future__ import generators def number(max): for i in range(max): if(i % 2 == 0): yield i, "Even" else: yield i, "Odd" for n in number(10): print n The output of this example is as follows: (0, 'Even') (1, 'Odd') (2, 'Even') (3, 'Odd') (4, 'Even') (5, 'Odd') (6, 'Even') (7, 'Odd') (8, 'Even') (9, 'Odd') It's basically a special case of an upward continuation (or is it downward? I'm bad with terminology). I think you can get pretty close to this behavior with streams, but it's still not as easy as a return statement that has a resume type thing. -- Dustin Sallings ------------------- To unsubscribe, mail caml-list-request@inria.fr Archives: http://caml.inria.fr Bug reports: http://caml.inria.fr/bin/caml-bugs FAQ: http://caml.inria.fr/FAQ/ Beginner's list: http://groups.yahoo.com/group/ocaml_beginners
