Preface

I used to write a lot of C and C++. My last major project before stepping into the world of Perl full time was an interpreted language that, among other things, drew diagrams, computed probabilities, and generated entire FrameMaker books. It comprised over 50,000 lines of platform-independent C++, and it had all kinds of interesting internal features. It was a fun project. It also took two years to write.

It seems to me that most interesting projects in C and/or C++ take months or years to complete. But it also seems to me that a whole lot of ideas that start out being mundane and uninteresting become interesting three-month projects when they are expressed in an ordinary high-level language.

This is one of the reasons why I originally became interested in Perl. I had heard that Perl was an excellent scripting language with powerful string handling, regular expression, and process control features. I learned Perl, and learned to like it, when I was thrown into a project in which most of my work involved slinging around text files. I quickly found myself spending hours writing Perl programs that would have taken me days or weeks to write in a different language.
