Previously we use vectors of objects and move semantics to handle ownership. That approach has the flaw that inserting an object into the middle of a vector, which may trigger a vector reallocation, can invalidate some addresses taken from instructions. Now the in-memory representation internally uses vector of unique pointers to handle ownership. Since objects are explicitly heap- allocated now, pointers to them won't be invalidated by vector resizing anymore.
