</div>I understand. OTOH this is a public beta where people are invited to<br>
use it for real, and <a href="http://pkg.racket-lang.org" target="_blank">pkg.racket-lang.org</a> already has many packages. If<br>
we had somehow painted ourselves into a corner where a required change<br>
had no (reasonable) backward compatibility tactic, people would (have<br>
to) understand and accept that. And in that case maybe we'd want to<br>
"re-launch" the package system as "Works only with 5.3.90 or higher",<br>
for sanity. But so far, in cases like multi vs. single collection<br>
default, or #:version, it's very much appreciated the intent has been<br>
to preserve it -- thanks!<br></blockquote><div><br></div><div>If having a beta period with a number of backward incompatibilities means having the best package system ever, I'm all for it. Twice.<br><br></div><div>Laurent<br>
