Isn’t this in the manual:

> Note that the local scope of a for loop body is no different from the local scope of an inner function.  
> [Scope of Variables · The Julia Language](https://docs.julialang.org/en/v1/manual/variables-and-scoping/#local-scope)

It’s the loop _body_ which has its own scope, so for scope purposes it’s the same as calling a function repeatedly.
