Like

irb(main):001:0> class Object
irb(main):002:1> def out(io = $stdout) io.puts(self) end
irb(main):003:1> end
=> nil
irb(main):004:0> fruits = %w( apple banana orange )
=> ["apple", "banana", "orange"]
irb(main):005:0> fruits.each &:out
apple
banana
orange
=> ["apple", "banana", "orange"]

?  Btw, I don't like _ either.

Kind regards

robert
