Value Oriented Programming Part V - Return of the Values

on YouTube ↗01h 42m

" summary

Argues for making types behave like values to reduce entanglement and accidental sharing, shows concrete fixes: a camera class trimmed of transient fields, a graph implemented as an adjacency matrix stored as bitset-backed vector with a maintained dimension invariant and a separate graph‑coloring solver (coloring is NP‑hard so solver is heuristic), a projector mapping pipeline that returns thousands of correspondences (move‑returned vectors instead of mutating members), and advocates separating calculating from doing plus move semantics to keep code local, testable and often faster (several O(n^2) to O(n) tweaks).
