Principles of Elegance
summary
Scala libraries Rapture use implicits, type classes and macros to push checks into the compiler: CSS macro validates properties at compile time, HTML5 nesting is enforced by types so illegal tag combos are compile errors and i18n strings promote language tags to types so accessing a missing locale is a compile error. The HTML builder compiles and works; design prioritizes small public APIs, fewer convenience overloads, and moving complexity into the library to reduce boilerplate.
