I cannot remember why, but a long time ago when learning Delphi 5 or 6, I have
learned not to call the destructor from within any method of the class, only
from outside. If this is no longer true nowadays (or maybe, has never been true
before), I'd like to use this solution.
Just to be sure we're talking about the same thing -- you think this code
should work:
type
TMyData = class
method: TMethodWithParameters;
a: whatever;
procedure Run;
end;
procedure TMyData.Run;
begin
method (a);
Self.Free;
end;
...
MyData := TMyData.Create;
MyData.a := ...;
MyData.method := @SomeMethodWithParameters;
TThread.Synchronize(NIL, @MyData.Run)

Why would this fail according to you ?
I have used this approach on multiple occasions.
