Checked PHP 5.2.1-dev (cli) (built: Dec 13 2006 08:24:06).
var_dump(Iterator instanceof Traversable) now returns false, also with
non-builtin (userland) classes, but should be true.
var_dump("Iterator" instanceof Traversable) now gives an fatal error
"instanceof expects an object instance, constant given". It should
accept the first operand as a string just like is_subclass_of does and
check if the class named "Iterator" subclasses/implements the other
operand.
$x = "Iterator";
var_dump($x instanceof Traversable) returns false. If $x is not an
object but a string it might want to behave like the former case
(string constant)?

This bug has been fixed in CVS.
Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at
http://snaps.php.net/.
Thank you for the report, and for helping us make PHP better.
This has been changed to throw a proper error message rather than the
uninformative one given. Perhaps in future versions this can be
changed to allow constant strings giving the expected output, but not
currently.
