Perl Style: Embrace Pattern Matching

Regular Expressions are your friend. More than that, they're a whole new way of thinking.
Just as chess players see patterns in the board positions their pieces control, Perl adepts look at data in terms of patterns.
Although most modern programming languages offer primitive pattern matching tools, usually through an extra library, Perl's patterns are directly integrated into the language core. /.../, $1, etc.
Perl's patterns boast features not found in other languages' pattern matching, features that encourage a whole different way of looking at data.
