final case class Cast(expr: Tree, tpe: Type) extends Value with Product with Serializable

Casts expr to the given tpe, without any check.

This operation is only valid if we know that expr is indeed a value of the given tpe.

Cast behaves like an unchecked AsInstanceOf, except that it does not convert null to the zero of primitive types. Attempting to cast null to a primitive type (that is not NullType) is undefined behavior.

Cast is not always a no-op. In some cases, a Cast may still have to be implemented using a conversion. For example, casting down from jl.Character to char requires to extract the primitive value from the box (although we know that the box is non-null, unlike with AsInstanceOf).
