I'm kind of surprised PBP would say that q{} is easier to read in this situation. IMHO, it seems to just adds noise.
i stick to using fat comma ( => ) only for key/value pairs. it has the side effect of quoting a bareword to the left which makes those pairs easier to read. so i never use it just for a comma though i have seen it used like that. this is definitely a matter of taste and i know mine is better than most! :)
as for q{} i stick to using it when there are quote chars in the string. i haven't had trouble reading '' (vs "" vs q{}) as the null string. pick a better font if you have trouble! :) also context (not perl but code in general) should make it easier to know when a null string is being used.
