Julia's loop scope behavior differs from Fortran?

Exactly. Put simply, no edit to the manual will help if people don’t know how to look up sections, just like with real books. You can put flashing neon lights on the section and it wouldn’t help if the reader hasn’t reached the page.
That’s not to say this can’t be improved ever. I just remembered this topic where it turned out typing == and === in the search bar didn’t return the right sections in Base or Manual.
