Effects and Resources: New Frontiers for Safe and Expressive Programming Languages

Explore the cutting-edge developments in effect typing and object capabilities in programming languages through this insightful lecture by Prof. Martin Odersky. Delve into the challenges of current effect typing systems, including the colored function problem and difficulties in combining different effect types. Discover how shifting focus from monadic effects to object capabilities can lead to improved effect polymorphism and flexible composition. Learn about the Caprese approach, which models captured capabilities in an experimental Scala extension. Examine how this method, combined with delimited continuations, enables the formulation of safe direct-style control effects, promising enhanced composability and flexibility in programming languages. Access accompanying slides for a comprehensive understanding of these new frontiers in safe and expressive programming.
