My vote is for keeping '='. It is very readable for counters as is 'in' for other containers.
Confusion? Considering the investment into learning all the new and powerful Julia language constructs, I don't see why exactly this elegant duality would be a problem for anyone. It is not even a documentation issue, the documentation is already crystal clear: "In general, the for loop construct can iterate over any container. In these cases, the alternative (but fully equivalent) keyword in is typically used instead of =, since it makes the code read more clearly" On Tuesday, October 27, 2015 at 10:55:23 PM UTC+1, Hai Nguyen wrote: > > > > On Tue, Oct 27, 2015 at 10:04 AM, Stefan Karpinski <ste...@karpinski.org > <javascript:>> wrote: > >> My general approach is to only use = when the RHS is an explicit range, >> as in `for i = 1:n`.
