Rails on ruby 2.4: Silence Fixnum/Bignum warnings

Wanna use the latest ruby, but don't really need to be perpetually reminded that rails hasn't caught up with this latest ruby design change? Change the top of your config/application.rb thusly:

require_relative 'boot'

verbose = $VERBOSE
$VERBOSE = nil
require 'rails/all'
require 'active_support/core_ext/numeric/conversions'
require 'active_job/arguments'
$VERBOSE = verbose
Bundler.require(*Rails.groups)

module MyApp
  class Application < Rails::Application
  end
end

Yes, this will also suppress any other ruby warnings from the loading of rails code. ¯\_(ツ)_/¯
