If you're not wring/changing the array no problems. But to be safe use Object#freeze... Terry Moore On 19/10/2011, at 6:26 PM, Michael Johnston <lastobelus@mac.com> wrote:
Note, in my example I can also guarantee that none of the elements in b are going to be changed (for example, an array of strings) Cheerio,

In ObjC, the immutable collections are threadsafe.
In macruby, are collections threadsafe to read only?
ie, if I do this:
a = [ ...] # an array that may or may not be changed
b = a.dup # nowhere in the code is b ever used to add/delete/change an element
is b thread-safe to read from multiple threads (queued operations/blocks)?
also, is there any difference between doing
b = a.dup
and
b = NSArray.arrayWithArray(a)
Both result in class Array, so I assume there is no difference.
Cheerio,
