BaseScope.nestedScopesNotSymbols is not exposed

[xied75]

In C#, to add a new namespace scope, I need to check currentScope if that already existed, but this nestedScopesNotSymbols is not exposed to me, we do have getNestedScopes but I don't want that, I just need to check one level.

Related, instead of List<Scope>, (in C# would be IList<IScope>), would it better to be IReadonlyList<IScope>? And if the list could grow big (guess only in theory), IReadonlyDictionary can be faster to query on?

Best regards,
