Immutable wrapper around Java arrays?

Question

Are there any immutable wrapper around Java arrays in Clojure, similar to Scala's ArraySeq?

What are your thoughts on introducing such a wrapper to Clojure's core?

Answer 1

It already exists, and has exactly the same name. The package is clojure.lang.

To use it, just call seq on the array - the result will be an instance of ArraySeq that wraps the array.

Note that the array is not copied so it shouldn't be modified by something else. Also, for primitive types there are custom classes, e.g. ArraySeq_int, but it's just an implementation detail - just letting you know so you don't start checking for (instance? clojure.lang.ArraySeq x).

Thanks Eugene, precisely what I was looking for!
