I think you're not even listing the most time-saving features of Perl. The examples you give are just peanuts, in my opinion. You're not even beginning to touch Perl's real strong points. For example, how many lines does it take to write a universal min function? Not many:

sub min {
    my $min = shift;
    foreach (@_) {
        $_ = $min if $_ < $min;
    }
    return $min;
}

There aren't many other languages that produce such a powerful function (the minimum of any number of items, the minimum value in an array, or a mix, like the minimum value in 3 scalars and 2 arrays) in so few lines.

And that's where my laziness lies.

Another example? Data::Dumper. Enough said.

• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
