Thanks! That was it!

Clojure 1.3.0:
user= (doc bit-or)
-
clojure.core/bit-or
([x y] [x y more])
Bitwise or
nil
user= (bit-or 1 1 1)
1
user= *clojure-version*
{:major 1, :minor 3, :incremental 0, :qualifier nil}
Clojure 1.2.1:
user= (doc bit-or)
-
clojure.core/bit-or
([x y])
Bitwise or
nil
user= (bit-or 1 1 1)
java.lang.IllegalArgumentException: Wrong number of args (3) passed
to: core$bit-or (NO_SOURCE_FILE:2)
user= *clojure-version*
{:major 1, :minor 2, :incremental 1, :qualifier }
So it looks like the ability to take more than two arguments was added
in 1.3.0 (and the doc-string agrees).

creating a finite sequence of uncertain length
I have a function without arguments which returns a big,complex object repeatedly until it returns nil. That is to say that the function will produce a sequence of objects, but I don't know how many. I want to call the generator as a lazy sequence but how do I make such a thing? Currently I am doing something like this: (loop [i (myfunc)] (if (nil? i) nil ;; we are done here (let ...do a bunch of stuff to i (recur (myfunc))) This works okay, but leaves that recur statement dangling at the end of the routine. What I would like to do is the cleaner: (doseq [ i (myseq)] ...do a bunch of stuff to i) I have tried using (def myseq (repeatedly (myfunc))), but the repeatedly doesn't seem to ever end. I have tried having myfunc return a nil, or a [] but it just keeps repeating the final end value of nil or []. How would you make such a terminating sequence? Is there a special final value myfunc must return so that the sequence ends gracefully? Or is this just an abuse of the concept of a sequence and I should just stick to the loop? thanks Blake -- You received this message because you are subscribed to the Google Groups Clojure group.

bit-or arity appears limited to 2 items
The bit-or arity seems to be limited to 2, rather than more, which seems to disagree with the documentation. I get Wrong number of args (3) passed to: core$bit-or for (bit-or 1 1 1). Have I misunderstood this operation; shouldn't it take any number of values? thanks Blake -- You received this message because you are subscribed to the Google Groups Clojure group.
