GiovanniThat was one of the things that I originally thought would weigh against this idiom, but found to my surprise that "Senders of" identified these references correctly-- I'd previously found symbols being included in my results and wondered why, but it looks as though someone was aware of this gotcha.
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: :)
