Summary
In this episode, Jason explores three important lambda enhancements introduced in C++20: default constructible stateless lambdas, assignable stateless lambdas, and lambdas in unevaluated contexts. He demonstrates how these features remove unnecessary language restrictions and enable new programming patterns. Using Compiler Explorer with GCC trunk, Jason shows how code that would fail in C++17 now compiles successfully with C++20, allowing default construction and assignment of capture-less lambdas.
