adress explicitly the problem of for loops in the REPL (ie global scope)

[reumle]

Having just wrestled with the global vs local issue in these for loops, my opinion is that the Julia Docs and tutorials

• should put this problem front and center as it will affect 100% of beginners
• be more solution oriented, with clear and workable examples, for said beginners.

In my opinion your great book (really!) would give another service to the Julia community if you did this....
Thank you!

Next revision will tackle the global vs local issue. I wait for the next major release of Julia because some things changed from Julia v1.0 to v1.1 to v1.2 ...
