I am working on smart pointers for FPC (something more than pure ARC for

This solution is full compatible with existing code base.
I would like to know what do you think about my conception and work.
First step is almost done -> new record operators:
=== begin code ===
{$MODESWITCH MANAGEMENTOPERATORS}
type // Record with automatic constructor and destructor
TValue = record
class operator Initialize(var aRec: TValue);
class operator Finalize(var aRec: TValue);
class operator Copy(constref aSource: TValue; var aDest: TValue);
end;
=== end code ===
MANAGEMENTOPERATORS are quite simple to implement. MANAGEMENTOPERATORS were
created initially for fast implementation of TValue in RTTI.pas, but they
inspired me for smart pointers.
This part I understand, it is simple enough. A managed record type ?
The second step is some concept of low level structures for smart pointers
(in this conception we have two kinds of smart pointers - smart pointers
for objects and smart pointers for pointers):
As I understand the code, this is the low-level basis for a managed pointer,
and by inference, a managed class. Is that correct ?
That would mean that the managed pointer/class would be implemented internally
using a 'managed record', correct ? I like this approach, quite ingenious :)
If so, please put the activation of the managed pointer feature under a modeswitch,
as Sven suggested. {$MODE DELPHINEXTGEN} or {$MODE OXYGENE} can simply allow this modeswitch.
And: keep up the good work :)
Michael.
