Dear Monks,

I would appreciate if someone could tell me what this warning means: "Reference found where even-sized list expected at filename.pl line 16"
Line 16 looks like: my %gGui = {};
I use it like this and so far I have not noticed anything wrong, but I would like to improve if I can: 
my $dest="";
$gGui{dest} = $dest;
$gGui{single} = 0;

In case it makes a difference, I work with Perl/tk.
Thanks,
Claire
