No, realized? works as intended on a single object. If you want to know if
there is an unrealized portion remaining of a sequence, just roll your own
function to step through it, being careful not to force realization of
unrealized portions while doing so. Untested example:
(defn seq-realized?
"Returns false if there is an unrealized tail in the sequence,
otherwise true."
[s]
(if (instance? clojure.lang.IPending s)
(if (realized? s)
(if (seq s)
(recur (rest s))
true)
false)
(if (seq s)
(recur (rest s))
true)))
