IIRC, glob iterates most slowly over its first (leftmost) iteration group,  {1,2,3} in this case, and more rapidly over each succeeding iteration group, so that the the last (rightmost) group  {I,II,III} iterates most quickly. This is the behavior I see in the output of your example code: the first (leftmost, arabic-number) field or column of each  "1aI" output record/string changes most slowly, the second (middle, alpha) changes more quickly, and the third (rightmost, roman-number) column changes fastest.

However, oysterperl, as shown in the example of desired output in the OP, seems to want the first (leftmost, arabic-number) column to change most quickly, the second (alpha) column to change most slowly, and the third (roman-number) column to change at an intermediate rate. Is it possible to produce this result with a glob solution? (The OPed example output also has commas separating the columns, but this is easily done with a glob template.)
