My answer was that you can never really know Perl.
<p>
This being said, I have:
<ul>
<li>Read a book on Perl (many books, in fact)</li>
<li>Written a book on Perl (yes, written one, but, well, on Perl 6 in fact, dunno if this counts; but I have also written many large tutorials on Perl 5)</li>
<li><i>not</i> contributed to the Perl source code (I doubt I'd be able to do so)</li>
<li>Debugged someone else's script (many times, including on various forums such as PM)</li>
<li>Played Perl Golf (yes, but only a little bit, I'm not really a great fan of that, but I like to write good concise code)</li>
<li>Used regular expressions to save the day (sure, a lot)</li>
<li>Used Perl for a certain amount of time (about 15 years by now)</li>
<li>Invested a certain amount of man-hours in learning Perl (sure, a fairly large amount of man-hours, most of which on my personal time)</li>
<li>Visited at least x Perl related events (yes, quite a number of them)
<li>(Co)maintain at least x active (up-river) CPAN modules (well, only one)</li>
<li>Forgotten you were not Larry Wall (oh, no, this I can't forget)</li>
<li>One can never truly know Perl (yes, I think so; at least, I'm pretty sure I won't ever truly know Perl, but that does not prevent me from using it successfully)
</ul>
