Overview

Callable

A lightweight mix‑in that gives any class a convenient class‑level ‘.call` helper.

class SendEmail
  include Callable

  def initialize(user)
    @user = user
  end

  def call
    Mailer.welcome(@user).deliver_now
  end
end

SendEmail.call(User.first)  # => delivers email
users.each(&SendEmail)      # => thanks to #to_proc

Compatible with Ruby 2.3+ and works the same on 3.x.
