Eww.
The more I think about it, the more I'm convinced that it's far
preferable to use a pure functional approach. Instead of fixing
(defn foo [x]
(with-open [bar (baz x)]
(make-some-lazy-seq bar)))
(map do-something-with (foo quux))
-> IOException: stream closed
with "resource scopes", or even with
(defn foo [x]
(with-open [bar (baz x)]
(doall (make-some-lazy-seq bar))))
(map do-something-with (foo quux))
isn't the truly functional way to use HOF like this?
(defn foo [x processor]
(with-open [bar (baz x)]
(processor (make-some-lazy-seq bar))))
(foo quux #(map do-something-with %))
