A demonstration of how Ruby's super keyword forwards on all arguments

# A demonstration of how Ruby's super keyword forwards on all arguments:

class A
  def foo(*args)
    puts "super class args are #{args.inspect}, block_given?: #{block_given?}"
  end
end

class B < A
  def foo(*argsb)
    puts "sub class args are #{argsb.inspect}, block_given?: #{block_given?}"
    super # argsb and any passed in block will be forwarded onto the super class's foo method
  end
end

b = B.new

b.foo(1, 2) { }
# Prints:
# sub class args are [1, 2], block_given?: true
# super class args are [1, 2], block_given?: true
