I need to take some time to check if the documentation would not benefit from a gigantic red box pointing out this `for` loop scope property. [It is not the first question this comes up.](https://discourse.julialang.org/t/i-thought-i-understood-pass-by-sharing-in-julia-until-i-found-this/46897/19) And it is also important [if you are dealing with closures inside a `for` loop too](https://discourse.julialang.org/t/i-thought-i-understood-pass-by-sharing-in-julia-until-i-found-this/46897/24). There is [a section of the manual that points out this scope property and also that you may reuse an existing variable as iterator with the keyword `outer`](https://docs.julialang.org/en/v1/manual/variables-and-scoping/#Loops-and-Comprehensions), but maybe it is not very noticeable.
