- Important: `CSTweak`'s closure is executed only just before the fetch occurs, so make sure that any values captured by the closure is not prone to race conditions. Also, some utilities (such as `CSListMonitor`s) may keep `CSFetchClause`s in memory and may thus introduce retain cycles if reference captures are not handled properly.
