Example's of how Ruby's super keyword passes on args and blocks

super.rb

class Foo
  def foo arg = false
    {arg: arg, block: block_given?}
  end
end

class Bar < Foo
  def foo *args
    super
  end
end
Bar.new.foo(true) { }
#=> {:arg=>true, :block=>true}

class Qux < Foo
  def foo *args
    super()
  end
end
Qux.new.foo(true) { }
#=> {:arg=>false, :block=>true}

class Bongo < Foo
  def foo *args
    super *args, &nil
  end
end
Bongo.new.foo(true) { }
#=> {:arg=>true, :block=>false}

class Wombat < Foo
  def foo *args
    super &nil
  end
end
Wombat.new.foo(true) { }
#=> {:arg=>false, :block=>false}
