A Kaleidoscope of C++ Lambdas
summary
Covers concrete lambda evolution and gotchas across C++11→C++26: shows how init captures let you move-only capture and how C++14 adds generic lambdas and parameter packs, C++17 adds copy-of-this and constexpr closure, C++20 brings explicit template parameters and better forwarding, and C++23 finally enables self-referential lambdas in C++23 for recursion. Demonstrates immediate invocation for constexpr/global initialization, replacement of std::bind with lambdas, and the frequent bug where capture defaults bite by capturing the surrounding object by reference, with fixes and idiomatic patterns.
