The article introduces Syl, a programming language that aims to encode compile-time computation using a modal type system inspired by two-level type theory. It explains how Syl uses mode axes (staticity and erasure) to classify values at compile time, enabling dependent types that are more expressive than current systems like C++ templates or Rust const generics.
Background
Dependent types and compile-time computation are active research areas in systems programming language design. Languages like Rust, C++, and Zig have incremental support, but full dependent type systems remain rare in practical languages.
