🤝 Use Forwardable for Delegation​

Instead of manually writing boilerplate methods to delegate calls to an internal object, leverage the Forwardable module. This makes your API clear and reduces repetition.

require 'forwardable'

class Report
  extend Forwardable
  def_delegators :@summary, :title, :lines_count

  def initialize(summary)
    @summary = summary
  end
end

summary = OpenStruct.new(title: "Q1", lines_count: 42)
report  = Report.new(summary)
puts report.title       # Q1
puts report.lines_count # 42
