Expressed without the interaction of dynamic bindings and laziness (which is why there’s the difference here), the question boils down to whether this is the correct, expected behavior or not:
boot.user=> (pr-str ["a" "b"]) "[\"a\" \"b\"]" boot.user=> (binding [*print-readably* nil] (pr-str ["a" "b"])) "[a b]" boot.user=> (binding [*print-readably* true] (pr-str ["a" "b"])) "[\"a\" \"b\"]" In other words, is the second expression expected (documented?) behavior?
