In this extract from the Stonehenge courseware for Learning Perl Objects, References and Modules, Schwartz covers everything you ever wanted to know about references, from basic usage to advanced techniques, including the Schwartzian Transform explained in graphic detail. Learn how to create scalar, array, hash, and subroutine references (including closures), pass them to and from subroutines, and build them up into multi-dimensional structures. Learn the art of using grep and map to select and alter these complex structures. Essential knowledge for any object-based or large program.
