Bellroy shares a Haskell technique using GHC 9.10's RequiredTypeArguments to create type-checked non-empty strings, replacing thousands of TemplateHaskell calls and improving build times by ~10%. This approach ensures invalid states are unrepresentable by enforcing non-emptiness at compile time through type families.
Background
The article discusses advanced Haskell type-level programming techniques aimed at improving code safety and compilation performance in large-scale applications.
