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:
