I'm not that familiar with HTTPClient.jl specifically, but usually if you have a stream of data you can do
JSON.parse(io) in a loop, and it will only block until the next JSON object is finished. Julia doesn't do much that's Clojure-like by default but you may be interested in Lazy.jl <https://github.com/one-more-minute/Lazy.jl>, which provides Clojurey features like lazy sequences and dynamic binding. I don't think it will solve your immediate problem, though. On 4 January 2015 at 06:15, C.
