I'm trying to modify/populate a hash in a subroutine, and I want to avoid using global variables since the sub may be in a separate module. Although the following code works, I KNOW there's a more elegant way to do this. Can anyone help? Thanks! 

$hash_ref = modifyHash(\%my_hash);
%my_hash = %{$hash_ref}; 
# hash is now modified

sub modifyHash()
{
  my $hash_ref = shift;
  my %sub_hash = %{$hash_ref};

  # Do something to the hash 
  $sub_hash{'test'}=1;

  return (\%sub_hash);

}
