title: Quantifier follows nothing in regex
body: <p>My requirement is to print the files having <strong>'xyz'</strong> text in their file names using <strong>perl</strong>.
  I tried below and got the following error</p>
  
  <p><strong>Quantifier follows nothing in regex  marked by &lt;-- HERE in m/* &lt;-- HERE xyz.xlsx$/;</strong></p>
  
  <pre><code>use strict;
  use warnings;
  
  my @files = qw(file_xyz.xlsx,file.xlsx);
  my @my_files = grep { /*xyz.xlsx$/ } @files;
  for my $file (@my_files) {
      print "The output $file \n";
  }
  </code></pre>
  
  <p>Problem is coming when I add <code>*</code> in grep regular expression. 
  How can I possibly achieve this?</p>
