With respect to large scientific/numerical programs, this safety mechanism _IS_ the big picture - or a large part of it anyway. It seems silly to me to introduce automatic generality to arbitrary rank arrays or arbitrary data types when such generality ignores the big picture - which is that few algorithms are stable (or even possible) in such generality. An algorithm which is fast and numerically stable on 2-d meshes may not even generate the right _sign_ bit on 3-d meshes - or may be _very_ slow to converge. In such a regime, J ignores the important points and provides irrelevant features. J. Giles
