Why should use warnings; go last? : <p>I vaguely recall that the <code>warnings</code> pragma should go last in the list of us modules being loaded with <code>use</code>.  I also vaguely remember that it has something to do with modules registering their own warning categories, but I can't reproduce any problems.  Can someone point to a relevant article or show an example where the placement of the <code>warnings</code> pragma makes a difference?</p>
