The title basically says it all, but here's some background:

I'm calling some code that expects to receive a hashref. (The XMLout method of XML::Simple, if you must know). I want to pass in a tied hash, since I want to control the order that keys come out when this code runs through them with each. Unfortunately, the code contains this construct:

  if (ref($ref) eq 'HASH') {
    # ... some code ...
    if (%$ref) {
      while (($key, $value) = each %$ref) {
        # ... recurse into the structure ...
      }
    }
    # ... some more code ...
  }

Now, the problem is that when I pass in a tied reference, it appears that %$ref is always false; that is, the code never even calls each on my tied hash.

Is there some magic method I'm missing to let me have scalar(%h) be true when %h is a tied hash?
