# `parse` can decode arbitrary JDN (Janet Data Notation) encoded by `string/format`

(def encoded (string/format "%j" @{:a 123 :b "foo" :c @{1 [1.2 2.3 3.4]}}))
# => "@{:a 123 :b \"foo\" :c @{1 @[1.2 2.2999999999999998 3.3999999999999999]}}"

(parse encoded)
# => @{:a 123 :b "foo" :c @{1 @[1.2 2.3 3.4]}}
