For 'auto'/magic: There's a looooot of material about pro and contra arguments, if you look at C#'s type inference. Replace auto x = ... with var x = ... and you can read a good amount of arguments about the benefits and (potential) downsides, and where people deem it useful and clear or where brittle and questionable.
