Aristotle
<p>That’s not a clear win. Because much CPAN-related infrastructure insists on a single dash, almost all modules have a single hyphen, which means the more fastidious form picks up nearly all descriptions correctly. If you allow multiple hyphens, you recover some false negatives, at the cost of some false <em>positives</em>, where the description of the module is malformed but there’s a line with multiple hyphens somewhere nearby. Matching <tt>' --? '</tt> at that point has a couple fewer false positives and still almost no false negatives.</p>
<p>But because of the effect of CPAN’s rules, it’s hardly worth bothering either way, and I prefer to get output that’s consistent with other tools.</p>
