Near the beginning of perlfunc, there is a section called "Perl Functions by Category". When I was first learning perl, I read that section at least once a week for several months. The familiarity I got with the kinds of things that perl's builtins do was immediately useful whenever I had an unfamiliar job to do.

Familiarity is the key. If you never do any low-level socket programming in perl, you'll never use connect or recv. Knowing they exist as a group assures you that perl can handle a job of that kind and that there are likely some higher level ease-of-use modules.

Many perl functions are derived from unix library or system functions. Learning to use them in perl is a great education in unix. If you know unix, you have a head start on learning perl.
