How to chain middleware call in Ruby?

chain_middelware_call.rb

# Create a middleware class
class Middleware 
  def call(*args) 
    puts "Args: #{args}"
    yield 
  end 
end

def call_in_chain(chain) 
  traverse_chain = lambda do 
    if chain.empty? 
      yield
    else
      chain.shift.call(chain.size, &traverse_chain)
    end
  end
    
  traverse_chain.call
end

# Example call
call_in_chain(Array.new(5) { Middleware.new }) { puts 'Finally the unit of work' }
