Dear experts:

I have a reference to a hash-of-hashes and need to delete from it. Deleting a leaf node is no problem: 
   delete ($HoHref->{$element}{$attr});

[download]
but deleting an entire element does nothing and returns no warning or error: 
   delete ($HoHref->{$element});

[download]
I don't think the leaf nodes have to be removed first, but in trying to do so, I found that this does nothing either: 
   $HoHref->{$element} = ();

[download]
Any clues would be most welcome! Thanks in advance,

Stephen
