You can do any of these:

# using a heredoc

print <<TEXT;
Once upon a time there was a little programmer that asked to many ques
+tions.
Today his question was realy a stupd one.
and so on and on...
TEXT

# using literal newlines in the text

print 'Once upon a time there was a little programmer that asked to ma
+ny questions.
Today his question was realy a stupd one.
and so on and on...
';

# using the comma operator

print "Once upon a time there was a little programmer that asked to ma
+ny questions.\n",
      "Today his question was realy a stupd one\n",
      "and so on and on...\n";

# using the concatenation operator

print "Once upon a time there was a little programmer that asked to ma
+ny questions.\n" .
      "Today his question was realy a stupd one\n" .
      "and so on and on...\n";

# using a custom sub. declare prototype so we can use it as
# a bareword. We use ^\n to mark our line wraps and remove 
# the leading whitespace on the next line. We use a regex
# to remove these and presto.....
sub wrap;
print wrap "Once upon a time there was a little programmer ^
            that asked to many questions.\nToday his question ^
            was realy a stupd one\nand so on and on...\n";

sub wrap {
    $text = shift;
    $text =~ s/\^\n\s*//g;
  return $text;
}

Update

You can even define your own custom print function that does the (un)wrap bit for you:

sub printw;

$interpolate = "Interpolate this\n";
$comma = "We can use the comma operator\n";
@ary = qw (this_ is_ an_ array);

printw "Once upon a time there was a little programmer ^
        that asked to many questions.\nToday his question ^
        was realy a stupd one\nand so on and on...\n^
        $interpolate^
        ", $comma, @ary;

sub printw {
    my @text = @_;
    s/\^\n\s*//g, print for @text;
}
