Hi,
I'm wondering whether (apply concat ...) can be re-written to be
lazy.
-------Expected behavior-------
(def temp (for [i (range 20)]
(do (println i)
[i i i])))
(def temp2 (apply concat temp))
Should print nothing.
-----Behavior in 1.1.0-RC-----
Under Clojure-1.1.0-rc, the operation was "somewhat" lazy.
Prints:
0
1
2
-----Behavior in 1.1.0------
The operation is eager.
Prints:
0
1
2
...
19
---------------------
I'm hoping it's possible to do this as it would be very useful, but
I'm not sure whether the semantics of apply allow this to be done. It
sort of half-worked in 1.1.0-RC so I'm optimistic.
Thanks for your opinions
-Patrick
