Is sound gradual typing dead?

Summary

The paper evaluates the performance of gradually-typed programming languages, particularly Typed Racket. It concludes that sound gradual typing faces significant challenges due to implementation overheads. The authors propose a method for evaluating performance and suggest further research to reduce overheads.

Key Takeaways

1. Sound gradual typing implementations suffer from performance overheads due to run-time checks.
2. The paper proposes a method for evaluating the performance of gradually-typed programming languages based on partial conversions from untyped to typed code.
3. Sound gradual typing faces significant challenges given the current state of implementation technologies.
