Algebraic Data Types + Pattern Matching = Elegant and readable Java code

Balkrishna Rawool

Data-oriented programming completely transforms Java maintainability. Combine algebraic data types and pattern matching to cleanly decouple domain structures from logic. Eliminate tedious manual type casting for good.
