Goffin


Goffin

(language)A definitional constraint language fordeclarative parallel programming. Goffin systematicallyintegrates equational constraints and functions within auniform framework of concurrent programming.

Goffin is an embedding of a functional language kernel(Haskell) into a layer of constraint logic, which allowslogical variables inside functional expressions. In orderto preserve referential transparency, functional reductionsuspends until logical variables become bound.

Logical variables are bound by equational constraints, whichimpose relations over expressions. Hence, constraints are themeans to structure the concurrent reduction of functionalexpressions.
