That is the expected behavior, but we wouldn't need to implement it that way. We could still implement it by calling the "is forcefully completed" metadata function, and so it wouldn't force the completion of the type. So a `true` return value would mean that the type has been forcefully completed, while a return value of `false` would mean that the type is complete (not just pretend-complete) **or** the completion of the type hasn't been attempted yet. Note that I'm not saying that this is how it needs to be implemented. However, I think its worth thinking about this, given that we're adding a new public interface and all. I think it comes down to the question of which situation would be more/less confusing to the (SB) user - querying a member/base class of an object and finding that it's incomplete (even though that is not possible in regular c++) - querying a member/base class of an object and finding that it's empty (even though the truth is that we just don't know what it contains.)
