Hi,<div>�I&#39;m a little surprised with the current SortedCollection #= implementation... it is:</div><div><br></div><div><div>= aSortedCollection</div><div><span class="" style="white-space:pre">	</span>&quot;Answer true if my and aSortedCollection&#39;s species are the same,</div>

<div><span class="" style="white-space:pre">	</span>and if our blocks are the same, and if our elements are the same.&quot;</div><div><br></div><div><span class="" style="white-space:pre">	</span>self species = aSortedCollection species ifFalse: [^ false].</div>

<div><span class="" style="white-space:pre">	</span>sortBlock = aSortedCollection sortBlock</div><div><span class="" style="white-space:pre">		</span>ifTrue: [^ super = aSortedCollection]</div><div><span class="" style="white-space:pre">		</span>ifFalse: [^ false]</div>

</div><div><div>�</div><div>and my surprise is because it compares the sortBlocks that makes the simplest case to fail like this one:</div><div><br></div><div>(SortedCollection sortBlock: [ :a :b | a &lt; b ]) = (SortedCollection sortBlock: [ :a :b | a &lt; b ])</div>

<div><br></div><div>One could argue that if we remove the sortBlock comparison then :</div><div><br></div><div><div>(SortedCollection sortBlock: [ :a :b | a &lt; b ]) = (SortedCollection sortBlock: [ :a :b | a &gt; b ])</div>

</div><div><br></div><div>would return true... but is that wrong? ... or is the philosophy to use the message #hasEqualElements: on this cases?</div><div><br></div><div>BTW, VisualWorks implementation is the same as pharo, but the BlockClosure&gt;&gt;= is different and that&#39;s why it works as at least I expected :-)</div>
