Can use `this` to refer index_identifier of repeat-count statement?

[Luther Lee]

For example, a callee action `foo` has a random variable `foo_val`. Then, another action calls `foo` in the repeat-count statement, using the `index_identifier` to constrain `foo_val`. For some reason, the name of `index_identifier` may be as same as `foo_val`.

action foo {
    rand int foo_val;
    ...
}

action main {
    activity {
        repeat (foo_val : 10) {
            do foo with { foo_val == this.foo_val; };
        }
    }
}

The question is, the built-in variable `this` can be used in this scenario?
Or I can only use different name for them?

repeat (i : 10) {
    do foo with { foo_val == i; };
}

It seems to hinge on whether or not the index_identifier foo_val is considered as a field of the containing action main{} and therefore included in the scope of 'this.' This has not been clarified as such in the LRM.
