      After a day optimizing ASTs, Magnolia now gets approximately 12x better compile-time performance for typeclass derivation than Shapeless!

      Magnolia has a significant advantage over Shapeless in that it knows a lot more at the same time, so it's able to do more optimizations.

      I've been saying "Shapeless/Kittens" a lot, but that's really just the clever magic which works on top of Scala's implicit search.

      And unfortunately, there's not a lot Shapeless can do to improve the performance of implicit search.
