In the fpc-rtl there is something like this:
procedure TObject.Free;
begin
if self<>nil then self.destroy;
end;
Does this make sense? i.e. How is it possible for self to be nil?
It happens when you try to free an object which either you didn't
create, or you've already set free.
The free method provides a nice way to save tests in your source code.
Destroy would rise an Access violation exception, Free doesn't.
