Persistence Object Simple

I am a perl amature and I am really having problems getting this module to work . whenever I use the ->Commit(Fn_"") method no code, after this command, is executed. Could anyone give me an example of working code how to save an array of numbers from 1..100 to disk using the Persistence::Object::Simple and also how to access this array using the ->load method. If anyone can help me I would be eternally greatful
