scala/scala3

Features

• JVM Bytecode Compilers - Compiles Scala 3 source code into Java bytecode that runs on the Java Virtual Machine.
• Contextual Implicit Resolutions - Implements a contextual abstraction mechanism using given/using clauses for compile-time implicit resolution.
• Type-Directed Implicit Resolutions - Resolves given instances and using clauses through compile-time type-directed lookup for contextual parameters.
• Sealed Hierarchy Desugarings - Compiles enum definitions into sealed class hierarchies with union type support for algebraic data types.
• Open Source Software - Developed and maintained by the Scala community under an Apache 2.0 license with an open contribution process.
• Functional Programming Concepts - Implements functional programming concepts including immutability, higher-order functions, and pattern matching.
• Source-to-Bytecode Compilers - Translates Scala 3 source code into executable bytecode, enabling developers to build and run applications.
• Algebraic Data Type Enumerations - Expresses algebraic data types through enum definitions that desugar into sealed class hierarchies with union types.
• Metaprogramming & Macros - Provides inline metaprogramming with staged evaluation on typed abstract syntax trees for compile-time code generation.
• Path-Dependent Type Systems - Enables types that depend on runtime values through path-dependent and singleton types for precise reasoning.
• Representation-Hiding Type Aliases - Hides underlying type representations while maintaining type safety through controlled visibility and separate compilation.
• Scala - An open-source, statically typed language combining object-oriented and functional programming for the JVM.
• Interactive Development Environments - Provides a built-in REPL for interactive code evaluation and experimentation.
• Deterministic Method Resolution Orders - Determines method resolution through a deterministic linearization order of trait mixins for super call chains.
• Statically Typed Languages - Enforces type safety at compile time with a sophisticated type system including traits, generics, and union types.
• Standard Libraries - Delivers a collection of reusable classes and functions that support common programming tasks.
• Dependent Object Type Compilers - Compiles Scala 3 source code into JVM bytecode using a dependent object type system and simplified syntax.
• Linearized Trait Mixins - Linearizes trait mixins following a specific ordering rule for deterministic method resolution and super call chains.
• Compile-Time Equality Guards - Enforces type-safe equality comparisons through a canEqual method preventing unintended type comparisons at compile time.
• Type-Safe Equality Enforcements - Enforces type-safe equality comparisons through a canEqual method preventing unintended type comparisons at compile time.
• Type-Level Conditional Logic - Enables type-level pattern matching for compile-time conditional type definitions and recursive type reduction.
• Language Release Highlights - Highlights the new language features and improvements introduced in the language.
• API Documentation - Ships searchable API documentation for every version of the standard library.
• API Documentation Generators - Produces API documentation for projects using the Scaladoc tool with new features.
• Source-Level Dependency Directives - Declares library dependencies in source files with directives resolved automatically at compile time.
• Progressive Lesson Series - Teaches the language through a series of short, structured lessons for progressive learning.
• Bite-Sized Tutorials - Introduces core language features through bite-sized lessons and short tutorials for newcomers.
• Language Specifications - Publishes a formal language specification defining syntax and semantics for tool builders and developers.
• Language Version Migrations - Provides a guide that helps move code from an older version of the language to a newer one.
• API Documentation Browsers - Provides searchable API documentation for every version of the standard library.
• Learning Resources - Offers structured language lessons and bite-sized tutorials for learning Scala 3 fundamentals.
• Migration Guides - Ships a dedicated migration guide for moving codebases from Scala 2 to Scala 3.
• Advanced Feature Documentation - Offers comprehensive documentation covering many of the language's advanced features.
• Idiomatic Coding Standards - Provides a style guide with conventions for writing clean, idiomatic code.
