zeltus has asked for the wisdom of the Perl Monks concerning the following question:

Once again it is Friday and my brain is fried. I have a number of arrays.. @a_1, @a_2,@a_3 I have a variable $n; How do I use it to access any of the three arrays as in $n = 2; print Dumper(@_$n); or even $y = "_" . $n print Dumper(@$y); (these don't work by the way - especially when "use strict" is in force. Which it is) I have done this, I know I have but I can't do it now. As I said, it's friday. As ever, all help gratefully received.
