Hi,
I came across this issue while implementing a lazy, efficient flatten that
also uses the whole sequence abstraction (flatten java arrays....).
The problem with (seq x) is, that it will throw an Exception if called on
something, that cannot be coerced to sequence, so I just used sequencial?
like the current implementation of flatten:
(defn my-flatten [coll]
(mapcat (fn [p] (if (sequential? (first p)) (mapcat my-flatten p) p))
(partition-by sequential? coll)))
But this will obviously fail to flatten anything that doesn't
implement clojure.lang.Sequential (like java.arrays).
