Are you looking for Patterns in Perl
? Many attempts have been made to collect those and name those, informally and formally. Most people look at the Perl Cookbook as a canonical example. Some have taken pattern names from books like the GangOfFour and applied them to Perl, although such actions are a bit questionable, as the problems that face Perl programmers are typically not aligned with the problems that face C++ programmers (for which the GoF book was written).
If you're simply looking at pattern names, your section will probably fail, as most Perl programmers don't go about naming things.
If you're looking for something else, you should attempt to describe it, again, using some different sort of strategy. Maybe an example: put up some code, and then show what the participants would supposedly do.
