I was thinking at something along the lines of objects also for instance:

$i = new Integer(33);

function foo(Integer $var) {
}

foo ($i); else it emits a fatal error. But also if you do

$i = "Name"; that would emit a fatal error because the value is
suposed to be an int. This might look a bit too much like java, but as
an extension it could be something quite interesting I believe.

String, Object, Integer, Scalar, Float  and what else.

So thinking of something like

$string = new String("Foo");
$string = "bar" or $string->setValue("Bar"); would do

$float = new Float(4.242);
$float->setValue('foobar'); // That emits an error
$float->setValue(3.14159);

echo $float; (__toString) or echo $float->getValue; to echo it's content/value

and so on.

Would that be "too" java-ish to be something considered in php6 ? ;-)
