propsal, have map accept array of method references to make chained mapping simpler with suggestion to implement it to behave like the &. operator so that intermediate nil values just ripple through as nil values proposal allow ~~~ ruby collection.map(&:instrument, &:issuer, &:name) ~~~ implementation is trivial this as a conceptual alternative to (with important remark is that if first or second mapping returns nil values the above code will break, forcing a much more verbose notation) ~~~ ruby collection.map(&:instrument).map(&:issuer).map(&:name) ~~~ proposal to be functional equivalent to ~~~ ruby collection.map { |e| e&.instrument }.map { |e| e&.issuer }.map { |e| e&.name } ~~~ proposal allow ~~~ ruby collection.map(&:instrument, &:issuer, &:name) ~~~ implementation is trivial
