Perl one-liners are a great way to learn more about Perl -- there is a lot of uncommon syntax that makes some of the more advanced examples more like little puzzles.

However, if you are not familiar with Perl, and fall to the common stigma that Perl is unreadable, I urge you to delve more into the modern Perl community. The community doesn't have the same tendencies towards built-in obfuscation anymore.
