No need to first require 'rubygems'?

I am currently reading through this guide: http://guides.rubygems.org/what-is-a-gem/

Under the third section ("Requiring code"), it says that if I run require 'rake', it should fail, because "because RubyGems isn’t loaded yet.". However, when I run require 'rake', (without running require 'rubygems', it works! Is the guide incorrect or am I using a wrong version of Ruby or has something changed?

If you have RUBYOPT=rubygems set in your environment when you launch Ruby, then Ruby Gems will automatically be required. Or if you launch ruby with the argument -rubygems, which is equivalent. Or if you're using Ruby 1.9 or later, Rubygems should automatically be required.

One (or more) of these things is probably true on your system.

You are probably running Ruby 1.9.

Per The RubyGems User Guide:

The default Ruby 1.9 package now includes RubyGems by default on most platforms (presently Debian based systems split this out into a separate package). This means that on Ruby 1.9 and above, you will not need to require 'rubygems' in order to load gem libraries.
