To use types nominally, you can proceed the type with an octothorp.ĭirectionHeading: (direction: #Direction) -> Nat These types will compile to the same type, which may be confusing to developers. Suite: type = Diamond | Spade | Club | Heart For example, if you have a type union specifying cardinal directions and another type union specifying suites of cards, these types will be compatible.ĭirection: type = North | East | South | West In some cases, structural typing can be error prone. The language encodes a set of laws which govern This order can be used to generalize or specialize a type. In Nomad, types are arranged into a lattice with a partial order. A lattice is a set with a preorder imposed on it. All types can be considered to be sets of values. The most simple model for implementing a type system employs sets as types. Types can be automatically generalized or specialized by moving up or down in the lattice. Nomad has a structural type system that is based on a lattice. Nomad is also an anagram for Monad which is primary structure in functional programming. Nomad was chosen to symbolise the portability of the language, principally the type system, which aims to provide type unification between many external type systems such as JSON, Protobuf, gRPC, and SQL. Nomad was originally created in 2018 as an experiment in lattice based type systems and type-safe uncertainty through probability monads. These concepts are recursion, pattern matching, and algebraic data types. There are three primary concepts at the root of the language. Nomad is designed to be a simple language.
