So Haskell got you all of the following: * GHC’s support for safe concurrent programming is world-class * Sound type safety led to refactoring being a breeze * Fun, stretches the mind (for some people) * Perfectly reliable unit tests. * Concurrent batched IO. * Abstractions for things like timeouts and running tasks on other threads while correctly bubbling failures. * Fantastic support for safely encoding and decoding JSON. * One of the best benchmarking tools I’ve ever used. And the complaints amounted to: * Devs have to think more about which String representation to use * Devs have to think more about syntactical differences from the more familiar C-derived languages * The team has to support more backend platforms, duplicate infrastructure * Not a mainstream language (harder to learn, hire for, bus factor) * “at this stage in my career I don’t want another programming language” 75% were for and 25% were against. Frankly the only complaints worthy of serious response were infrastructure duplication and hiring/skill development/bus factor. The rest are people just being close-minded and lazy.
