Maybe I have misunderstood, but my understanding
of #sample! is that it DOES modify the receiver
(i.e. the array, by deleting the elements
returned) and is otherwise functionally identical
to #sample. I would have thought that was a
receiver-modifying version of #sample.

In your email of Mon, August 04, 2008, 01:31:00,
you said:

Have I missed something?
