Issue #8361 has been updated by alexeymuranov (Alexey Muranov). =begin From the top of my mind, i can propose only this: p = lambda [x]->{ # ... } foo([1, 2, 3]) [x]->{x*x} (i didn't like the new lambda syntax anyway:) ). =end ---------------------------------------- Feature #8361: Alternative syntax for block parameter https://bugs.ruby-lang.org/issues/8361#change-39099 Author: alexeymuranov (Alexey Muranov) Status: Feedback Priority: Normal Assignee: Category: syntax Target version: =begin I propose an alternative syntax for block parameters: p = lambda [x] { # do whatever you like with x here, but be sure to return the result } instead of p = lambda { |x| # ... } This would be consistent with the syntax of procedure call: (({p[a]})). Also, compare: a_bunch.each [element] do # ... end with: a_bunch.each do |element| # ... end =end -- http://bugs.ruby-lang.org/
