🌀 Dynamic Dispatch with Method Objects

Storing method objects in collections enables dynamic dispatch and decoupling. You can queue or filter operations as first‑class entities rather than stringly‑typed method names.

class TaskRunner
  def initialize(tasks = [])
    @tasks = tasks.map { |obj, meth| obj.method(meth) }
  end

  def run_all(*args)
    @tasks.each { |m| m.call(*args) }
  end
end

runner = TaskRunner.new([[Logger.new, :info], [Notifier.new, :send_email]])
runner.run_all('Hello')
