I mean, if one does

It really doesn't matter whether the reference MyObject is set to nil before
or after the call to Free ?
Sadly, it does, although I do not think it is a good programming practice.
See my first mail in this thread ;-)
My collega explained to me what you meant (your original statement was not
clear to me).
You're referring to cases like:
Var
MyForm : TMyForm
destructor TMyForm.Destroy;
begin
MyForm.Something;
end;
and then somewhere
FreeAndNil(MyForm);
Which is simply wrong coding in the destructor.
I don't think you should provide for this. This is encouraging people to
write bad code. They should get an error, and correct their code.
