Interesting! To my mind that definition is incorrect. I would expect the sender of a block to be the sender of the enclosing method, in which case the definition would arguably be<br>
<br>
BlockClosure methods for accessing<br>
sender<br>
^self home sender<br>
<br>
A block activation's caller would be it's sender slot, so within a block you might refer to thisContext caller. But what is arguably a bug in my implementation is that within a block activation thisContext sender refers to the caller (the sender of value: to the activation's block) not to the sender of the enclosing method.<br>

How about instead of faking out BlockClosure>>sender we fix MessageTally along the lines of:<br>
<br>
MessageTally>>tallySendsTo:inBlock:showTree:<br>
<br>
prev := aBlock asContextWithSender: thisContext.<br>
<br>
This should work just as well if I understand the intent of the change correctly.<br></blockquote><div><br></div><div>That's right. In the Teleplace codebase we simply use asContext:</div><div><br></div><div>tallySendsTo: receiver inBlock: aBlock showTree: treeOption</div>
