Ruby allows this. Both arrays and hashes provide an each method and include the Enumerable module.

Ruby even makes it invisible because of destructuring assignment of block variables.

    ruby-1.9.2-p180 > {1=>2}.each {|k,v| puts "#{k} #{v}"}
    1 2
     => {1=>2} 
    ruby-1.9.2-p180 > {1=>2}.sort.each {|k,v| puts "#{k} #{v}"}
    1 2
     => [[1, 2]]
