Current Release v1.3.0 (October 4, 2015)¶ ↑

• Pattern match now check arity of pattern and block

• PatternMatching::ALL pattern now should be presented as variable length args (*args)

• NoMethodError and ArgumentError raised from method block won’t be catched anymore by lib

Release v1.2.0 (July 10, 2015)¶ ↑

• Record classes can be declared with a type/protocol specification for type safety.

• Improved documentation

Release v1.1.0 (August 12, 2014)¶ ↑

• A simple implementation of tuple, an immutable, fixed-length list/array/vector-like data structure.

• FinalStruct, a variation on Ruby’s OpenStruct in which all fields are “final” (meaning that new fields can be arbitrarily added but once set each field becomes immutable).

• FinalVar, a thread safe object that holds a single value and is “final” (meaning that the value can be set at most once after which it becomes immutable).

Release v1.0.0 (July 30, 2014)¶ ↑

• Protocol specifications inspired by Clojure protocol, Erlang behavior, and Objective-C protocol

• Function overloading with Erlang-style function pattern matching

• Simple, immutable data structures, such as record and union, inspired by Clojure, Erlang, and others
