title: RegExp error in Perl
body: <p>Binding a regexp to a parameter in perl, I'm getting the following error:
  <code>syntax error at ./ctime.pl line 23, near "/^\((\d{2}):(\d{2})\)/)"
  Execution of ./ctime.pl aborted due to compilation errors.</code></p>
  
  <p>Here is the line where I try to bind it:</p>
  
  <p><code>$_[0] =~ /^\((\d{2}):(\d{2})\)/)/;</code></p>
  
  <p>I'm trying to match an hours/minutes combination in parens, such as <code>(99:99</code> or <code>(01:24)</code>. There will always be four digits.</p>
