A more simplictic alternative could be to have objects (declared to be
managed) managed in the same way as ansistrings.

This would be easy to implement since the ansistring facilty could be

Also a block of memory could be declared to be managed in this way.

Drawback for objects is that they could not refere to other objects in a
circular manner, so this has to be handled manually.

This feature could be especially useful for functions which returns objects
or memory chuncks of arbitrary size like bitmaps.
