selectors to select for. note that [route2] does not "normalise" any selectors, such as "bang" including implicitly 0-argument "list" messages and such. almost like [route], but preserves message as-is, and uses the true selector. rejected messages it's basically the same as this message will be checked for true selector as [gf/selector] does, then that selector is checked against a list of selectors and the unaltered message is output by the appropriate outlet. accepted messages (outlets are in the same order as the object's arguments). exact input selector is output as-is.
