In this case I would also use puts ary, of course, but there is cases like

%w(foo bar qux).each { |file| require file }

where you would also be able to do

%w(foo bar qux).each(&method(:require))

In that case I would still prefer the more explicit block form.

Sorry, if that didn't come out too clear in my previous post.
