Forwarder3

This implementation is for, and needs, Ruby 3.1

Abstract

Ruby's core Forwardable gets the job done(barely), but produces most unreadable code.

Performance

Execution time is that of 85~95% of Forwardable by evalling strings whenever possible.

How does it work?

Let us speculate about that:

As simple as it gets

Given a class

require 'forwarder'
class MyClass
  extend Forwarder

  attr_reader :string

  forward :length, to: :@string
  forward :len, to: :string, as: :length

  def initialize; @string = 'Robert' end
end

Then it forwards as expected

  expect(MyClass.new.length).to eq(6)
  expect(MyClass.new.len).to eq(6)
