-The arguments n and m must be of integer type.
-A run-time panic occurs if n
-is negative or larger than m, or if n or
-m cannot be represented by an int.
+The size arguments n and m must be integer values.
+A constant size argument must not be negative, and
+if both n and m are provided and are constant, then
+n must be no larger than m.
+If n is negative or larger than m at run time,
+a run-time panic occurs.
