ie. if I have the following:

```auto

return Array.append<Project>(theProjectsNew, [newProject]);

```

which appends a new object “newProject” to an array called “theProjectsNew”

and replace it with:

```auto

let theProjectsBuffer : Buffer.Buffer = Buffer.Buffer(theProjectsNew.size());

for (x in theProjectsNew.vals()) {

theProjectsBuffer.add(x);

};

theProjectsBuffer.add(newProject);

return theProjectsBuffer.toArray();

```

the programatic results are the same … and the warning goes away … is this a valid way forward? and leave things otherwise as stable arrays?
