Excellent!

Ah yes, Doug caught that one already, but thanks anyway.

>* Changed:
>-    elsif (UNIVERSAL::isa($root, 'UNIVERSAL')) {
>+    elsif (UNIVERSAL::can($root, $item)) {

The only problem with this is that it doesn't allow AUTOLOAD methods
to work.  I've already had to change this line (several times in fact!)
to work around a problem with CGI which returns false when asked
isa('UNIVERSAL') on the second or subsequent calls.  The current test
is UNIVERSAL::can($root, 'can') which seems to work OK, even though it
is a little contrived.

Thanks for the patch.
