Re^2: Printing from three arrays

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.)

I checked the glob page, and I could not find something that would make it change it's ways, so you would need to split and join it :( `perl -e '@_=split(/=/, $_) and print join(", " ,@_[2,0,1]),"\n" for glob "{a,b,c}={I,II,III}={1,2,3,4}"'` it's cumbersome, though. I tried something with unshift pop but it was longer. `perl -E '@_=split /=/ and unshift(@_,pop @_) and say join ", ", @_ for glob "{a,b,c}={I,II,III}={1,2,3,4}"'` `perl -E '@_=split /=/ and say join ", ", unshift(@_, pop @_) && @_ for glob "{a,b,c}={I,II,III}={1,2,3,4}"'`	[reply] [d/l] [select]

Not really much (if any) better: `c:\@Work\Perl\monks>perl -wMstrict -le "use 5.014; ;; print s{\A(.+?),(.+?),(.+?)}{$3,$1,$2}xmsr for glob '{a,b,c},{I,II,III},{1,2,3,4}'; "` [download] (I won't show the output; it's as expected.) Give a man a fish: `<%-{-{-{-<`	[reply] [d/l] [select]
