I use it in Clojurescript for a custom tuple type.
For small number of items, deftypes are way faster to create and access
than PersistentVectors. I use tuple type e.g. for returning multiple values
from a function. Implementing #[] allowed me to have a compact syntax for
creating and destructuring such tuples.
(defn foo [a b]
#[(+ a b) (- a b) (* a b)])
(defn foo []
(let [#[plus minus times] (foo 1 2)]
(str "bla bla" plus "blaah" minus)))
