From: matz@... Date: 2020-06-09T01:00:12+00:00 Subject: [ruby-core:98684] [Ruby master Feature#16939] Alias _1 as _ for block numbered params Issue #16939 has been updated by matz (Yukihiro Matsumoto). Status changed from Open to Closed It was the first candidate for a single anonymous block parameter. But we abandoned for the compatibility's sake. Too many existing programs use `_` as a local variable (far too more than `_1`). We'd be happy to be proven wrong. If someone is willing to experiment and to find the solution to solve the compatibility problem, please reopen the issue. Matz. ---------------------------------------- Feature #16939: Alias _1 as _ for block numbered params https://bugs.ruby-lang.org/issues/16939#change-86030 * Author: x3qt (Yury Polyakov) * Status: Closed * Priority: Normal ---------------------------------------- I propose to alias `_1` as `_` for block numbered params, so the following statements should be equal ��� ``` ruby [1,2,3].map { _1 ** 2 } [1,2,3].map { _ ** 2 } ``` There is an [anonymous function argument literal](https://clojure.org/reference/reader#_dispatch) in Clojure and it feels natural all the way, hope we can have the one too. -- https://bugs.ruby-lang.org/ Unsubscribe:
