-So this is a call to the `apply` method of the companion object of the `List` class. That method takes an arbitrary number of arguments and constructs a list from them. Every collection class in the Scala library has a companion object with such an `apply` method. It does not matter whether the collection class represents a concrete implementation, like `List`, or `LazyList` or `Vector`, do, or whether it is an abstract base class such as `Seq`, `Set` or `Iterable`. In the latter case, calling apply will produce some default implementation of the abstract base class. Examples:
