📐 Transparent Delegation with Forwardable in Modules

Use Forwardable or SingleForwardable to define delegate methods cleanly, avoiding method_missing overhead. This yields explicit, performant delegation inside modules or classes.

require 'forwardable'

module CacheProxy
  extend Forwardable
  def_delegators :@store, :[], :[]=, :delete

  def initialize(store)
    @store = store
  end
end

class Session
  include CacheProxy
end

Clients of Session get direct calls to the underlying @store methods.
