One of the problems we face at Stonehenge as professional trainers is to make sure that we write materials that are reusable in more than one presentation. The development expense of a given set of lecture notes requires us to consider that we’ll need roughly two to four hundred people who are all starting in roughly the same place, and who want to end up in the same place, and who we can find in a billable situation.

With our flagship product, the Learning Perl course, the selection of topics was easy: pick all the things that nearly everyone will need to know to write single-file scripts across the broad range of applications suited for Perl, and that we can teach in the first week of classroom exposure.

When choosing the topics for Intermediate Perl, we faced a slightly more difficult challenge, because the “obvious” path is far less obvious. We concluded that in the second classroom week of exposure to Perl, people will want to know what it takes to write complex data structures and objects, and work in groups (modules, testing, and distributions). Again, we seemed to have hit the nail on the head, as the course and book are very popular as well.

Fresh after having updated our Learning Perl and Intermediate Perl books, brian d foy realized that there was still more to say about Perl just beyond the reach of these two tutorials, although not necessarily an “all things for all people” approach.

In Mastering Perl, brian has captured a number of interesting ...
