I used the wrong word 'reference' it should have been variable. I've tried to impliment your code below, but I'm still lost...
foreach $argnum (0..$#ARGV){ print "$ARGV[$argnum]\n"; my $path=$ARGV[$argnum]; @path=split /\//,$path; $node=node->{$_} for @path; print $node; } print "\n"; }

    got it! phew!
    foreach $argnum (0..$#ARGV){ $node=$ret; print "$ARGV[$argnum]\n"; @path=split /\//,$ARGV[$argnum]; print Dumper @path; #debugging helps! $node=$node->{$_} for @path; print $node; } print "\n"; }
      Just a minor note: your way to iterate thru different arguments by index is rather cumbersome

      just do

      ~$ perl -E 'foreach $arg (@ARGV) { say split /\//,$arg }' 1/2 a/b/c 12 abc

      And plz consider using strict and warnings!
