title: Concatenating strings with spaces in Perl. Any built-ins?
body: <p>In Perl I can concatenate multiple strings with spaces between them as follows:</p>
  
  <pre><code>my $long_string = $one_string . " " . $another_string . " " . $yet_another_string . " " . 
  $and_another_string . " " $the_lastr_string
  </code></pre>
  
  <p>However, typing this is a bit cumbersome.</p>
  
  <p>Is there a built-in that can make this task easier?</p>
  
  <p>e.g. something like:</p>
  
  <pre><code>concatenate_with_spaces($one_string, $another_string, $yet_another_string, ...)
  </code></pre>
