definitional constraint programming

(DCP) A declarative, programming paradigm which integrates concurrent constraint programming, constraint logic programming and functional programming. In this setting a concurrent constraint language becomes a coordination system that organises the concurrent interaction of parallel functional computations. The language is also a generalisation of parallel functional programming languages, such as Id, where constraints and constraint abstractions are reused to define new constraints, as the means of programming logical variables for parallel coordination.

Goffin is a DCP language.
