Third Dunaj experiment: Protocols First One of Dunaj’s objectives is to facilitate host independent style of programming. The third Dunaj experiment aims to transform core API into one that uses protocols for all of its abstractions. Additionally, Dunaj introduces a concept of a factory protocol that represents an abstraction of a constructor for an abstract data type. Protocols and protocol methods are part of the Dunaj’s interface that is oriented towards implementers of custom types and language extensions and they are documented separatedly in the SPI part of Dunaj’s documentation.
Goals of the third Dunaj experiment are as follows: - Provide protocols for all existing built-in abstractions that were in Clojure specified by host interfaces. - Modify existing core functionalities to build upon protocols instead of specific types, host classes or interfaces. - Introduce a separate representation of deftypes, treating the underlying host class as an implementation detail not automatically imported into the current namespace. - Introduce a new idiom of factory protocols, which are used to represent an abstraction of a constructor for an abstract data type.
