`instanceof` operator does not trigget class loading:
-----------------------------------------
class X {}
function __autoload($name) {
echo "Loading $name...\n";
}
$x = new X();
if ($x instanceof X) {
echo 'x is X';
}
if ($x instanceof NonExistingClass) {
echo 'blarg';
}
-----------------------------------------
The same applies to argument types.

This would certainly be a nice feature.
However, keep in mind that it is not always possible to tell whether something
is a class or an interface.
For example, when doing something like this, we can't tell whether 'A' is an
interface or a class:
if ($a instanceof A) {
}

Yes, there is a use case.
Currently, I use a workaround but in general, the idea behind is that after I
locate the file, corresponding to the class name being autoloaded,
I require_once the file and then check if the class is really inside
(class_exists). As of 5.4, class_exists returns false for traits and I have to
use
class_exists || trait_exists. Not a big deal, really, but it is still possible
to
have different paths for classes (ex. /classes) and different one for traits
(/traits).

Sorry.. it should say "It is NOT a critical feature" instead of "NOW".

It is now a critical feature but it would be nice. For example - if I decided
to format the filenames depending on what is being autoloaded
(class/interface/trait) I could not easily do it.
Adding a second argument to the autoload callback would make this possible and
should not break anything.

Could you elaborate a bit on the usecase?
Until now, there didn't seem to be the need to handle interfaces differently in
an
autoloader. Why would you treat traits differently from classes and interfaces?
