From [developer's meeting log](https://docs.google.com/document/d/1q22gVRNbCIYOQw2djH4UPmT0gxVoBKvjvs0MqX5ILcU/pub): > 2.7 or later > knu: Introducing ��������� (as in Lua) would allow for writing this way: ary.each { puts(...) } > Matz: Allowing omission of ���self��� sounds like a bad idea because that makes each(&:puts) and each(&.:puts) look very similar but act so differently. The last Matz's notice makes a lot of sense for me, so I withdraw my petition for `self`-less operator :) ---------------------------------------- Feature #13581: Syntax sugar for method reference https://bugs.ruby-lang.org/issues/13581#change-75780 * 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:
