Lightning Talk: The Decade Long Rewind: Lambdas in C++
summary
Survey of lambda changes from C++11→C++20 with concrete claims and examples: lambdas produce unique unnamed closure types so two identical lambdas have different closure types, captures support value/ref and mutable semantics demonstrated by a small snippet that mutates a captured-by-value copy, C++14 adds default params generic lambdas and generalized/move captures, C++17 brings constexpr lambdas and capture of this by value, C++20 adds template-style lambdas and parameter-pack captures enabling compile-time algorithms via constexpr lambdas and it shows these techniques actually compile and run.
