Small ad of mORMot (main author Arnaud Bouchez aka ab) :

with SynCommons module you have nice utils for such things:

procedure MyProc;
var
  list: TList;
begin
  with TAutoFree.One(list, TList.Create) do
  begin
    list.Add(x);
    { ... some other stuff with list here }
  end;  // <-- here is called list.Free
end;

There is also nice module AutoScope which uses management operators (!) by
Dmitriy Pomerantsev aka pda0:
