The basic fact is that an array is an array and a set is a set Sure,
the implementation could vary, depending on performance constraints. What
he (and others) have asked for is any solution (or reference to a solution).
A lot of us would like to see it. I haven't tackled core data or BigTen
yet, so I don't know what is involved. I just know I'm going to have to
crack that nut sometime soon. Fortunately, my current stuff is mostly in
the small array ( <100 ) category.
