What Haskell Taught Us When We Weren't Looking
summary
Haskell’s concrete influence on mainstream languages is spelled out: a 2,000-line C++ configurator is refactored into composable functions; Java, Scala and Swift borrow first-class functions and pattern matching; generics and local type inference trace back to Haskell-inspired tradeoffs; using non-empty list types eliminates head-of-list errors by construction; abstractions like Monoid/Monad and higher-kinded types enable reusable pipelines; libraries cited include QuickCheck, lenses, streaming packages and STM; remaining pain points are records, modules, GC and IDE support.
