Scala Rock-Painting

" summary

Argues that Scala lets teams mix object and functional styles and that static typing plus implicits bring power and danger: code can compile yet behave unexpectedly because of apply inference, optional parentheses and underscore shorthand causing silent runtime bugs. Describes a Java-to-Scala project using the Typesafe stack (Spray, Play), Cake pattern and Spring interop, notes slower compilation but fewer state bugs when using immutability, cites Amdahl-style scaling surprises (many cores give little speedup if code locks), and documents learning with Anki.
