Loops have their own scope as of Julia 1.0. I’m a bit puzzled about why the first loop works, but there’s tons of discussion about this, cf [this](https://github.com/JuliaLang/julia/issues/28789), [this](https://discourse.julialang.org/t/new-scope-solution/16707), and [this](https://discourse.julialang.org/t/another-possible-solution-to-the-global-scope-debacle/15894). I’ll bet the answer lies somewhere in there, but hopefully someone else can explain.

(Note though that (I don’t think) either of those solutions I linked were implemented)
