Another pretty unholy idea: resemble the way Ruby docs document the methods: ```ruby [1,2,3].map(&Math#sqrt) %w[foo bar baz].each(&#puts) ``` Yes, it conflicts with comment syntax, but in fact, no sane person should join the comment sign immediately after non-space symbol. And we already have parsing ambiguities like this: * `foo -bar` �����`foo(-bar)`; * `foo - bar` �����`foo.-(bar)`. ---------------------------------------- Feature #13581: Syntax sugar for method reference https://bugs.ruby-lang.org/issues/13581#change-66435 * 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:
