<div>Traditionally, Smalltalk-80 has had a single global namespace for classes, but I think Squeak and Pharo are running Environments now, which breaks up the single class namespace in a way familiar from languages wherein one must include xyz in order to get access to certain state and behavior. <br>
<br>Hopefully this helps, as confusing as it is. <br><br>On Jun 23, 2013, at 1:41 PM, Azka Niazi <<a href="mailto:azka.akn@live.com" target="_blank">azka.akn@live.com</a>> wrote:<br><br></div><div></div><blockquote>
