return any arbitrary Perl value. If the corresponding operation for this value
is overloaded too, that operation will be called again with this value.
+As a special case if the overload returns the object itself then it will
+be used directly. An overloaded conversion returning the object is
+probably a bug, because you're likely to get something that looks like
+C<YourPackage=HASH(0x8172b34)>.
