Would love to see see either one implemented at this point. Not having an ergonomic way for functional composition is a pain. My dream: ~~~ slug = title .then(&:strip) .then(&:downcase) .then(I18n:::transliterate) .then(Utils:::hyphenate) .then(Validations:::check_length) .tap(PostLogger:::info) ~~~ ---------------------------------------- Feature #13581: Syntax sugar for method reference https://bugs.ruby-lang.org/issues/13581#change-74822 * Author: americodls (Americo Duarte) * Status: Open * Priority: Normal * Assignee: * Target version: ---------------------------------------- Some another programming languages (even Java, in version 8) has a cool way to refer a method as a reference. I wrote some examples here: https://gist.github.com/americodls/20981b2864d166eee8d231904303f24b I miss this thing in ruby. I would thinking if is possible some like this: ~~~ roots = [1, 4, 9].map &Math.method(:sqrt) ~~~ Could be like this: ~~~ roots = [1, 4, 9].map Math->method ~~~ What do you guys thinking about it? -- https://bugs.ruby-lang.org/ Unsubscribe:
