Issue #16667 has been updated by jgomo3 (Jes=FAs G=F3mez). Hanmac (Hans Mackowiak) wrote in #note-8: > @jgomo3 i found my old Symbol#call code > = Great helper. Well, that is another way. So yes, the whole point of this ticket is to propose to allow that kind of = expressions. In other words, to enable us programmers to prepare, to "partially" call, o= r to "curry" better the thing that would be a method call based on a symbol= for any purpose. So e.g, using the extension designed by (Hans Mackowiak), my example use ca= se would be: ```ruby ary.map(&:dig.(:thing, :id)) ``` And for getting the partial proc: ```ruby dig_thing_and_id =3D :dig.(:thing, :id).to_proc ``` And for comparison, the idea as I explained: ```ruby ary.map(&:dig.to_proc(:thing, :id)) dig_thing_and_id =3D :dig.to_proc(:thing, :id) ``` ---------------------------------------- Feature #16667: Allow parameters to Symbol#to_proc and Method#to_proc https://bugs.ruby-lang.org/issues/16667#change-84466 * Author: jgomo3 (Jes=FAs G=F3mez) * Status: Open * Priority: Normal ---------------------------------------- Allow parameters to Symbol#to_proc and Method#to_proc So we can say: ``` ruby ary.map(:dig.to_proc(:id)) ``` Instead of ``` ruby ary.map { |e| e.dig(:id) } ``` Oppening the posibilities to refine the `&` operator in the future, for som= ething like: ``` ruby ary.map(&(:dig, :id)) ``` Related: * https://bugs.ruby-lang.org/issues/11161 * https://bugs.ruby-lang.org/issues/16435 -- = https://bugs.ruby-lang.org/ Unsubscribe: <mailto:ruby-core-request / ruby-lang.org?subject=3Dunsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
