The corecursive list; i.e. the arguments to
unfoldsaved off to a data structure. Generally does not have methods itself; as with scalaz.NonEmptyList, it provides typeclass instances instead, and you typically import typeclass syntax to get methods.The corecursive list can be a very efficient way to represent "listlike" things in some cases; because it is so unlike "normal" collections, though, it's important to understand how its operations are implemented and what their performance characteristics are going to be. For example, using
consiteratively to add a bunch of elements to the beginning of a scala.collection.immutable.List is very efficient; it's very inefficient for corecursive list.Operations are generally designed to preserve the isomorphism with scalaz.EphemeralStream; for example,
apcould be a "zipping"ap, but instead is a less efficient "combination" style. This means that the scalaz.Monad has the same behavior as that of scalaz.EphemeralStream and more traditional strict list structures.
