Yes, and it is even more general: have a look at method #badSelectors for  
example, and check the senders of one of the symbols in this list. If a  
method refers (anyhow) to a symbol, the latter is considered a (potential)  
sender.

So you can find the #mySymbol sender when you use it in (myObject perform:  
#mySymbol), but the same goes for (myCollection select: #mySymbol).

BTW I whish that Marcus would read this thread, he invented  
Symbol>>#value: :)
