Oh, of course. That is fixed in the patch.

I think it has the same advantages over try...finally as any use of 'with' has. CleanupManager would allow to use 'with' instead of 'try..finally' in many cases where this is currently not possible, so unless the introduction of 'with' itself was a mistake, I think this is just taking a step along the path that has already been chosen.
