Well, It's confusing, I admit, but "ditto for symbols" means: If you
have a *list* containing only a symbol like "mysym" and a symbol
containing "mysym" as data part ("symbol mysym") they are treated the same. 

So "list mysym" and "symbol mysym" are equivalent. However a message
of just "mysym" is neither a  list- nor a symbol-message, instead it
is a "mysm"-message. You can use [route mysym] to grab

Look here: http://puredata.info/dev/PdMessages/ for a broader

As a general hint: Quite often it is useful to prepend [route] with
[list trim] and stop worrying about the bomb, err, the list-messages:

 [list trim]
 [route freq pitch note]
