I wanted to know if you could arbitrarily pass a block to an overridden method via "super". It seems like an obvious "yes", but my curiosity got the better of me once more. Normally you call "super" with no arguments. Don't recall ever seeing it invoked with a block. So there you have it...

override-inherited-method-ad-hoc-block.rb

class Base
  def deploy(&block)
    puts "work"
    yield if block_given?
    puts "done working"
  end
end

class Derived < Base
  def deploy
    puts "overridden"
    super
  end
end

class Derived2 < Base
  def deploy
    puts "overridden with block"
    super { puts "hiya" }
  end
end

Derived.new.deploy # => overridden
                   #    work
                   #    done working

Derived2.new.deploy # => overridden with block
                    #    work
                    #    hiya
                    #    done working
