i have many structures like this (yes, in delphi):

function TXList.Lock: ILock;
begin
  result := TLock.Create(self);
end;

procedure dostuff;
begin
  list.Lock;
  // use the locked list
  // when ILock is out of scope, unlocks the list
end;

i know the obvious solution is to assign it:

procedure dostuff;
var
  l: ILock;
begin
  l := list.Lock; // assign it
  // use the locked list
  // when ILock is out of scope, unlocks the list
end;

but it is a lot of work (it is a big project) and my pals are not so happy
):-\

Porting from what? Delphi? Are you sure that it didn't on Delphi by
> accident?


i really don't know if it was accident, but we found it useful.
