Project Valhalla: Value Types, Nullability and Float16

An airhacks.fm conversation with Paul Sandoz (@paulsandoz) about:
Project Valhalla's origins and goals, value types vs reference
types, heap and stack flattening optimizations, Value objects and
data transfer objects, nullability constraints, enums and values,
implicit constructability, potential performance gains, challenges
in retrofitting value types into Java, implications for numeric
types and operator overloading, connections to Vector API and
Project Panama, impact on JVM languages like Scala, timeline and
development process for Project Valhalla, potential for improving
Java's competitiveness in areas like machine learning, challenges
in growing the Java language in an extensible way, considerations
around backwards compatibility, Paul Sandoz's role in the project
and future directions for Java
