(shamelessly plagarized from 'Programming Perl, 3rd Edition', p. 756.) all variables in the base class are declared using our so they're visible to the other packages. > 'Why "class"?' it's an extension of the 'divide and conquer' technique to coding i described in step 1. if all your code is crammed into one script, editing, making changes, finding bugs, etc. can be a nightmare. spreading the code (and effectively, the tasks) out over several classes makes it easier and also makes the code reusable. > 'Why not CGI.pm?' i do use cgi.pm, but only to read in the form parameters. please read about why i use html::template for more clarification (it's in the introduction). > Can the presentation not be simplified so that we see the solution to the > primary problem first, and then have the decorations explained afterwards, > with reasons as to why they are better than the original. probably not, since i'm writing all this on the fly. in other words, had i prepared the entire tutorial in advance, this would be possible. but since i'm writing and releasing each step one at a time, it's not exactly feasible. > I am acquainted with perl modules and subroutines, and find it confusing > when a module is mistaken for a class, or a subroutine for a method.
