Scala's powerful compile-time type manipulation tools allow developers to enforce type safety and create robust domain-specific languages, enhancing the capabilities of the language immensely.
Type constraints using =:= and <: provide a mechanism for developers to define relationships between types, enabling functions to check for type equivalence and subtyping at compile time.
With type-level conditionals introduced in Scala 3, developers can utilize match types to create intricate type logic that operates similarly to pattern matching in value-based logic.
By using type classes, Scala promotes flexible design patterns that empower developers to define behavior based on the types instead of being tied to concrete implementations.
