To allow that, `.:puts` should be a sole expression by itself. However ruby has the line continuation for ���fluent interface��� (like https://bugs.ruby-lang.org/issues/13581#change-74822), for a decade. If `.:` will be introduced, I think it should obey that syntax too, and allowing it without the receiver feels confusing. > Is it a voluntary design decision, or limitation of what can be parsed? It is easy to add a receiver-less syntax. https://github.com/ruby/ruby/commit/2307713962c3610f4e034e328af37b19be5c7c45 ---------------------------------------- Feature #13581: Syntax sugar for method reference https://bugs.ruby-lang.org/issues/13581#change-74865 * 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:
