You're not recursively filling a recursive data structure though, so the routine should not be passing data to merge: it should either be accessing a single reference and updating in place, or accessing a global (gack!).

For example: 

my %global_data;
fill_recursively(\%global_data, 10);
sub fill_recursively {
  my $data_href = shift; # hashref to modify
  my $count = shift; # what level are we
  push @{$data_href->{"key $_"}}, "level $count" for 1..$count;
  fill_recursively($data_href, $count - 1) if $count > 1;
}
use Data::Dumper;
print Dumper(\%global_data);

The push is accessing the global data directly. Put whatever you want in there. Does that help?
