OK thanks Bob, I'm sure Harlan will pipe up if there

Since you invited me, ROW always returns an array, ROWS always returns a
scalar. ROW can cause problems when nested in some other functions. ROWS
may be slower, and it may use more memory, but it's generally more robust.
So would you prefer slower correct results or quick errors?
