IMO it's not a good idea to recommend the use of `alias this`.  It's a
neat trick that solves the short-term problem, but in the long term it
actually becomes a maintenance burden.  I would recommend instead
avoiding such tricks that save a bit of typing in the short-term but
causes problems down the road.  (I used to love using `alias this`, but
over time have become convinced that it's not worth it.  It makes code
needlessly obscure and reduces understandability.)
