The Most Valuable Values
summary
Argues that value semantics belong at the architectural level and demonstrates a concrete C++ implementation: a unidirectional data flow using std::variant for actions, an update reducer that returns new models, and a single mutable state that drives rendering and intent. Ships a small ncurses counter and an asynchronous store implemented as Lager with an enabled time-travel debugger exposed over a REST API, using immer::vector to keep history efficiently; shows undo/redo and a text editor handling gigabyte files and reports benchmarks/paper backing performance.
