ATS-first

ATS is a programming language equipped with a highly expressive type system rooted in the framework Applied Type System to unify implementation with formal specification. In ATS, a variety of programming paradigms are supported in a typeful manner, including functional programming, imperative programming, object-oriented programming, template-based programming, modular programming, etc. ATS has moved on to become ATS2, which can be found at http://ats-lang.org. What is stored here is now referred to as ATS0-Proto. It is mostly kept as a reference so as to provide some historic details on the development of ATS.
