... The rules are defined in a NetCore-like AST [11], and then used to issue flowmods to a switch in our Controller monad. Controller is essentially a writer monad, but the key point is that Haskell’s type checker can identify which fields are used for matches (M), actions (A), or both (MA). The Control ...

C Sharp (programming language)
C# (pronounced as see sharp) is a multi-paradigm programming language encompassing strong typing, imperative, declarative, functional, generic, object-oriented (class-based), and component-oriented programming disciplines. It was developed by Microsoft within its .NET initiative and later approved as a standard by Ecma (ECMA-334) and ISO (ISO/IEC 23270:2006). C# is one of the programming languages designed for the Common Language Infrastructure.C# is intended to be a simple, modern, general-purpose, object-oriented programming language. Its development team is led by Anders Hejlsberg. The most recent version is C# 6.0, which was released on July 20, 2015.
