Carrier classes are Project Amber's current idea to extend some of records' benefits to regular classes. Probably the most important among them is deconstruction, which would allow classes to participate in pattern matching and reconstruction. In recent weeks, there have been two mails to the Amber mailing list that describe that idea, and in this episode we discuss them both as well as the evolution between them. We also hear why syntax discussions often provide negative value and get a sneak peak at what will likely be the next Project Amber language feature.

In this "Ask the Architect" episode of the Inside Java Podcast, Nicolai Parlog talks to Brian Goetz, Java Language Architect at the Java Platform Group at Oracle.
