I copied the below code directly from the docs in Collections and Data Structures: Iteration. next = iterate(iter) while next !== nothing (i, state) = next # body next = iterate(iter, state) end I defined iter as iter = 1:3 I’ve tried running it in its own file and in the REPL, and in…

julia> iter = 1:3 1:3 julia> while next !== nothing global next (i, state) = next # body next = iterate(iter, state) end julia> Above also works.

julia> let next = iterate(iter) while next !== nothing (i, state) = next # body next = iterate(iter, state) end end julia> Above works for me.

This works for me as well. Do you have any idea why it’s the case that you are able to test the value of next before defining it, or why the code from the docs does not work?

Thank you. That clears up my confusion.
