What’s the motivation for this?

I guess in 2.11, unused wasn’t part of lint, but is there a particular problem with it (asking because I’m in the process of enabling it on all my projects!)

This now warns on unused parameters, vals and implicits according to scalac -xlint:help

Right, but that sounds like a good thing to me. Where does that cause problems?

I got quite a few seemingly related to simulacrum:

[error] /home/travis/build/typelevel/cats/core/src/main/scala/cats/Apply.scala:10: parameter value ev$macro$3 in method ap is never used
[error] @typeclass(excludeParents = List("ApplyArityFunctions"))

And implicit evidence that are not "in use" like

[error] /home/travis/build/typelevel/cats/core/src/main/scala/cats/data/Validated.scala:421: parameter value NT in method apply is never used
[error] def apply[A](f: => A)(implicit T: ClassTag[T], NT: NotNull[T]): Validated[T, A] =

Ah I see. We have some evidence parameters that we don't directly use.

There's some related discussion here. It sounds like scala doesn't offer great options for selectively ignoring these. Unless someone sees a better option, I'm fine with this change coming in as-is.

@kailuowang @ceedubs perhaps we should keep an eye on this PR as it might help with Simulacrum-related warnings
