Traffic log of Yosemite performing auto-save to iCloud (as discovered by https://datavibe.net/~sneak/20141023/wtf-icloud/). Unsaved documents are automatically uploaded to iCloud *before* the user has selected where they would like the document to be saved (interestingly, actual file contents are uploaded to S3).

landonf / TypeClassTag.scala

Created October 14, 2014 20:20

Automatic boxing and unboxing of an instance that conforms to a typeclass, and the typeclass itself.

	object example {
	import scala.language.higherKinds

	object @@ {

	case class TypeClassManifest[V, T[_]](value: V)(implicit val typeClass: T[V])

	def apply[V, T[_]](instance: V)(implicit T: T[V]) = TypeClassManifest(instance)

	implicit def typeClass[V, T[_]] (manifest: TypeClassManifest[V, T]): T[V] = manifest.typeClass

	typealias BoundT = T
	func array () -> Array<BoundT> { return [] }
