The speaker demonstrates how combinators (C, W, S, Sigma, Psi) from combinatory logic appear naturally when composing these algorithms, using a live array language REPL. Key insights include: filter is just replicate with a unary predicate; C++'s unique is really an adjacent filter; chunk/chunk-by/chunk-by-key follow the same argument-type pattern; and C++ range projections are essentially the Psi combinator. The talk argues that understanding algorithm families by their argument types — rather than memorizing names — gives a transferable mental model across any language. ## Full article daily.dev links to this article rather than hosting it.
