This is a sore spot that has been discussed many times on this list[1]. The short version is that many people agree that the name "contains?" is misleading to newcomers, but according to Rich it's not changing any time soon[2]. What you want for linear searches is 'some (as mentioned in the doc for 'contains?).
Also, why are you quoting your vectors (e.g. '[:a :b :c] instead of just [:a :b :c])?
