You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: callbacks.rb
    path of file: ./repos/hyperstack/ruby/hyper-state/lib/hyperstack/internal
    
    the code of the file until where you have to start completion: module Hyperstack
  module Internal
    module Callbacks
      if RUBY_ENGINE != 'opal'
  
    
        def define_callback(callback_name, before_call_hook: nil, after_define_hook: nil)
          wrapper_name = "_#{callback_name}_callbacks"
          define_singleton_method(wrapper_name) do
            Context.set_var(self, "@#{wrapper_name}", force: true) { [] }
          end
          before_call_hook ||= lambda do |_name, sself, proc, *args|
            sself.instance_exec(*args, &proc)
            args
          end
          define_singleton_method("_#{callback_name}_before_call_hook", &before_call_hook)
          define_singleton_method(callback_name) do |*args, &block|
            args << block if block_given?
            send(wrapper_name).push args
            Hotloader.when_file_updates do
              send(wrapper_name).delete_if { |item| item.equal? args }
            end
            after_define_hook.call(self) if after_define_hook
          end
        end
