The programming language Syl is being developed to incorporate compile-time dependent types, a feature that aims to enhance systems programming by allowing computations to be encoded within a modal type system. This approach draws inspiration from two-level type theory and modal logic, enabling values to have modes that describe properties like staticity and erasure. These modes dictate whether a value is known at compile time (static) or runtime (dynamic), and whether it is retained or discarded after compilation (unerased vs. erased). By leveraging these modes, Syl can achieve compile-time specialization and implement dependent types, where the return type of a function can vary based on the value of its input. AI
