Hi everyone,

if you pass a right instance of class to a function , how can that
class not be loaded already?
for example:
function foo(Foo_Bar $a) {
}
how can you pass a Foo_Bar instance to function foo without
Foo_Bar class already defined?
Because Foo_Bar could be *defined* under a different name, say,
Foo_Blah. Then, as soon as someone needed Foo_Bar, we would use
class_alias to add an alias. That is, as soon as someone tried using
Foo_Bar it would turn out that Foo_Bar and Foo_Blah are the same class
and all Foo_Blah objects are *also* Foo_Bar objects and everything is
cool. Therefore foo(new Foo_Blah()) would work (if there was autoload).
Please see the demo I provided at https://bugs.php.net/bug.php?id=61422
Then again, at least it's consistent with instanceof. Where calling
autoload by default is probably indeed unacceptable.
This is complicated.
