I can see that you really want this feature, this is for sure.

However, nowhere you write WHY you need this feature; 

The behaviour you seem to expect is wrong by definition.

As stated: 
There are *no* leaks. The memory is freed at procedure exit; 

This is just a little later than what you expect. (you expect it right after the :=Nil;) 
So WHY do you expect/need this behaviour ? 

What architectural decision makes this necessary ?

I am asking this because I find it hard to believe that you would
write conciously code which really depends on this feature.
