🧱 Ensuring Isolation with Anonymous Modules

Anonymous modules (modules without a name) can encapsulate behavior without polluting your application namespace. They’re excellent for one-off mixins or temporary behaviors in tests and scripts.

handler = Module.new do
  def process(data)
    data.upcase.reverse
  end
end

class Processor
  include handler
end

puts Processor.new.process('abc')

Since the module has no constant name, you avoid naming collisions and keep your global namespace clean.
