In fact I was hoping to get the pipe operator introduced in ruby. (Created an issue with that in mind: https://bugs.ruby-lang.org/issues/14392). Taking that pipe operator example as an operator that sends messages maybe we can use it to send a message to the class or module. Like this: ``` ruby :sqrt |> Math ``` Since `Math` is not a method the message would extract the method from the object. If this is not practical maybe we could invert the operator and do: ```ruby Math <| :sqrt ``` ---------------------------------------- Feature #13581: Syntax sugar for method reference https://bugs.ruby-lang.org/issues/13581#change-69771 * 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:
