I cannot remember why, but a long time ago when learning Delphi 5 or

have learned not to call the destructor from within any method of the

has never been true before), I'd like to use this solution.
If it is the last thing you do in the method, there is no problem.
Note that "Free" itself is a method that calls Destroy (the actual
destructor), so the advice you got was strange to say the least :-)
To be precise: as long as you don't access Self after a Free (this
includes calling virtual methods, but not non-virtual ones) this is no
problem. This has been this way in both FPC and Delphi since the
beginning of TObject.
