Issue #13581 has been updated by tom_dalling (Tom Dalling). What about triple colon `:::`? ```ruby [1,2,3].map(&Math:::sqrt) [1,2,3].each(&:::puts) ``` `::` is for looking up constants, so it kind of makes sense that `:::` is for looking up methods. ---------------------------------------- Feature #13581: Syntax sugar for method reference https://bugs.ruby-lang.org/issues/13581#change-66436 * 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: <mailto:ruby-core-request / ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
