GoKawiilNew Syl language adds modal type system for compile-time dependent types
A developer is building Syl, a programming language that encodes compile-time computation using a modal type system with two mode axes: staticity (static vs dynamic) and erasure (erased vs unerased). The project's compiler is available on GitHub, and its design draws on András Kovács' two-level type theory research and plans for OxCaml.
