The article explores how different type classes in Haskell (Functor, Applicative, Monad) enable different forms of static analysis through their computational contexts. It explains how applicatives allow for static analysis of effects while monads don't, using a practical interface example. The post builds on existing knowledge about effect systems and static analysis in functional programming.
Background
In functional programming, particularly in Haskell, there's ongoing discussion about how different abstractions (Functor, Applicative, Monad) affect the ability to analyze code statically. Applicatives are known to preserve static analysis capabilities while monads generally don't due to their sequential nature.
