</div>And when issue of usability doesn't even get considered until a few<br>
years later when the user (or a colleague) gets an email suggesting<br>
the results can't be be reproduced ...?<br>
<br>
I'm inclined to add both an option (to specify a seed, replacing the<br>
environment variable) and a flag (to seed from the system clock or<br>
whatever), and having the PRNG generate a fatal error if neither of<br>
those are used.<br>
<br>
That way, neither of the likely problems can arise by oversight.<div class="yj6qo ajU"><div id=":25s" class="ajR" tabindex="0"></div></div></blockquote></div><br></div><div class="gmail_extra">This looks very good at first glance.<br>
