selectors to select for. note that [route2] does not "normalise" any selectors, such as "bang" including implicitly 0-argument "list" messages and such. rejected messages almost like [route], but preserves message as-is, and uses the "list" selector except for bang float symbol pointer. message will be checked for true selector as [gf/selector] does, then that selector is checked against a list of selectors and the message is output on the appropriate outlet. accepted messages (outlets are in the same order as the object's arguments). selector is modified according to the following rule : apart from bang float symbol pointer, everything else becomes 'list'. (intended to go with [unpack]).
