[fpc-pascal] Re: operator overloading and counting references / creating / destoying anonymous instances

[Jorge Aldo G. de F. Junior]

Imagine the following :

A -> C -> E
B -> D -> E

A is ref counted, and says that theres 10 references to the object C
B is ref counted, and says that theres 5 references to the object D

But both C and D points to the same object !

So now you have actually 15 references to the same object.

Lets say objects gone out of scope and C is now counted at 0 on A, what to do ?

Deallocate C causes E to be deallocated, but, what happens at B -> D ?

So what you need ?

A -> Singleton -> E
B -> Singleton -> E

In other words, make an object that stores all bignums and decides
when to allocate or deallocate then and work from that on.
