It doesn't get that far for me as you dropped the line terminating semi-colons
You are assigning constants to nothing $list is a scalar take a look through perldata for further info
Though I think you might want to use square brackets [ ] or an array

perl -we 'use strict;
my $list = [2,3,4,5,6];
my @list = [2,3,4,5,6];
print "$list \n";
print join ",", @{$list};print "\n";
print @list,"\n"'

Take a look through perlref for further info on references and accessing their values.
