I?m happy with doing nothing here.  But, IF we do something, start with a single-image routine only. 

The advantage of an intrinsic is that it provides a portable calling sequence.  And the user does not need to be concerned about finding and linking a library.  We have other, similar, intrinsics.  MATMUL, for example.  Certainly the ?use case? of sorting a numeric array exists.  The question is whether the advantages of making that operation an intrinsic is sufficient motivation for making this a feature. 

Cheers,
Bill
