Scope of "struct" and "macro"

General Usage
1

In the tree of scopes at Scope of Variables · The Julia Language , in branch 5, what means “don’t allow nesting” ?
That “struct” and “macro” don’t allow nesting of other scope blocks inside them?

2

It means you can only use these constructs at the top-level global scope, not inside of for loops, for example.

Thanks. So then that “(don’t allow nesting)” is redundant, strictly speaking, as the fact you state is already mentioned by the 1st branch of the tree
