title: How to use Perl's File::Grep module
body: <p>I am using the <a href="https://metacpan.org/module/File::Grep" rel="nofollow"><code>File::Grep</code></a> module. I have following example:</p>
  
  <pre><code>#!/usr/bin/perl
  use strict;
  use warnings;
  
  use File::Grep qw( fgrep fmap fdo );
  
  my @matches = fgrep { 1.1.1 } glob "file.csv";
  
  foreach my $str (@matches) {
      print "$str\n";
  }
  </code></pre>
  
  <p>But when I try to print <code>$str</code> value it gives me <code>HEX</code> value: <code>GLOB(0xac2e78)</code></p>
  
  <p>What's wrong with this code?</p>
