Principles of Elegance
summary
Argues that Scala lets libraries hit an elegance zone by combining concise syntax with strong typing and shows concrete Rapture work: a CSS string-context macro that validates CSS at compile time, an HTML DSL with nesting constraints enforced by types, and extensive use of implicits, type inference, type classes, value classes and occasional macros to implement modular serializers and nicer compiler diagnostics; advocates minimal public APIs, use-site-first design, and retrofitting capabilities without breaking users.
