It's the Zip module namespace. If you write a program, Test, a class such as Settings can cause problems. Using a module: module Test class Settings end end Test::Settings will not cause definition problems with other programs that use the same class name: Settings. -- >here are more things in heaven and earth, horatio, than are dreamt of in your philosophy.
