HOLY UNICODE!! ---------------------------------------- Feature #12240: circle number arguments https://bugs.ruby-lang.org/issues/12240#change-57904 * Author: Nobuyoshi Nakada * Status: Open * Priority: Normal * Assignee: ---------------------------------------- Often improvements about implicit block argument have been proposed, but in vain. Such as: ~~~ruby [[1, 2], [3, 4]].map {|a1, a2| a1+a2} #=> [3, 7] ~~~ to ~~~ruby [[1, 2], [3, 4]].map {_1+_2} ~~~ Now, we (ko1 and nobu) found and propose the *perfect* solution. ~~~ruby [[1, 2], [3, 4]].map {���+���} ~~~ `���`..`���` denote the arguments upto 20. https://github.com/ruby/ruby/compare/trunk...nobu:feature/number-arg -- https://bugs.ruby-lang.org/ Unsubscribe:
