Remember, this is for GUI stuff. In some cases the code actually uses the
new return pointer, for example when you want to interact with the
recently added GUI element, but sometimes you can just "fire and forget"
it, like injecting an icon. In this case the constructor of the object
adds it to some globally maintained object tree, so it's not lost or
remain dangling. Then you can access it from there with various utility

This is something quite specific, and I actually wonder if it's a corner
case we don't handle or PurePascal's implementation is less restrictive.
