Deprecated and Inherited implicits

@deprecated("Use explicit Equiv.universal instead. See Scaladoc entry for more information: ".+("https://www.scala-lang.org/api/current/scala/math/Equiv$.html#universalEquiv[T]:scala.math.Equiv[T]"), since = "2.13.0")
implicit def universalEquiv[T]: Equiv[T]
Deprecated
[Since version 2.13.0]

This implicit universal Equiv instance allows accidentally comparing instances of types for which equality isn't well-defined or implemented. (For example, it does not make sense to compare two Function1 instances.) Use Equiv.universal explicitly instead. If you really want an implicit universal Equiv instance despite the potential problems, consider implicit def universalEquiv[T]: Equiv[T] = universal[T].
