(Full disclosure - I've got a vested interest in statistical
applications of matrices)

Having documented/packaged RCLG and fully read RCL, I just want to
note that yes you could use them for arrays in CL with exactly what
you want, it would be silly (the prime use for them is to handle the
features in R that CL doesn't yet have natively -- one of these days
CL will).
