Hi Marcin,<br><br>I'm not a fan of using #become. I will use it for very specific behavior<br>when I need to retain pointers to an object. For example for implementing a<br>proxy. In that case become is a very useful tool. I think that #become is<br>
overkill for this situation, but I won't argue that it doesn't work. In<br>most cases you have a well encapsulated collection. That collection is not<br>referenced outside the object so you can just reinitialize your collection</blockquote>

<br>without #become. If it is complicated enough to worry about pointers I<br>wouldn't use #become. Someone will get lost and miss your #become hidden<br>inside #removeAll: . I'm not saying this will cause problems but I think I<br>
would rather work with the collection directly instead of using the #become.<br><br>Also if you are working on a collection that is large enough to worry about<br>performance then you are probably missing a database that would<br>
significantly improve your performance.<br><br>Ron Teitelbaum<br><br><br><br>________________________________________<br>From: <a href="mailto:beginners-bounces@lists.squeakfoundation.org">beginners-bounces@lists.squeakfoundation.org</a><br>

butI'd interested to see if it's a good use of #become:... Does it<br>keep references ? is it safe ?<br><br>Thanks<br>_______________________________________________<br>Beginners mailing list<br><a href="mailto:Beginners@lists.squeakfoundation.org">Beginners@lists.squeakfoundation.org</a><br>
