+1 @Tom Breloff . I was confused about this when starting out. Comparing `for i in 1:3` vs `for i = 1:3`, even though I regularly use matlab if you think about it for `i = 1:10` doesn't really make a lot of sense. It would be nice if it was just one way as opposed to the confusion about whether = or in should be used.
