Issue #6242 has been updated by jacketskingdom (Jackets Kingdom). i agree with you and see more about punk clothing. https://jacketskingdom.com/collections/punk-leather-jacket ---------------------------------------- Feature #6242: Ruby should support lists https://bugs.ruby-lang.org/issues/6242#change-102842 * Author: shugo (Shugo Maeda) * Status: Rejected * Priority: Normal * Target version: 2.0.0 ---------------------------------------- I've heard that Ruby is a LISP. LISP stands for "LISt Processing." Hence, Ruby should support lists. I've attached a patch to add the classes List and Cons, and the cons operator `:::'. Example:
S[1,2,3].inject(:+) => 6 S[1,2,3] => S[1, 2, 3] 0 ::: S[1,2,3] => S[0, 1, 2, 3] 0 ::: 1 ::: 2 ::: 3 ::: nil => S[0, 1, 2, 3] S[1,2,3].inject(:+) => 6
