Xronos will still be developed. I see Xronos incorporating the recent
laziness changes at some point, but I also see it going in a more
dynamic direction. By this I mean less dependent on the proprietary
IFunction and ISequence interfaces. Currently they are modeled after
and used similarly to the IFn and ISeq interfaces in Clojure. With the
laziness changes ISequence will behave more similarly to the standard
IEnuerable/IEnumerator interfaces. And IFunction makes no since when
compiling to the DLR.
