From: mpapis@... Date: 2018-02-01T22:05:37+00:00 Subject: [ruby-core:85329] [CommonRuby Feature#13581] Syntax sugar for method reference Issue #13581 has been updated by mpapis (Michal Papis). Not sure it's worth it - but while we are at this thinking of a shorthand one of the proposals `&Math&>sqrt` made me think if it could be automated and all the iterators could recognize methods and we could avoid the initial `&` to this `map(Math...)` - skipped the operator as it's not clear what's preferred. My two cents to the operator - what about `!` and `@` would they conflict? (yes for the Kernel, not sure about Class'es). ---------------------------------------- Feature #13581: Syntax sugar for method reference https://bugs.ruby-lang.org/issues/13581#change-70115 * 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:
