t_CaseInsensitive

NAMESPACE
namespace blueplanet;
class Animal {
public function saveTheWorld($when) {
}
}
$animal = new blueplanetAnimal();
$animal->saveTheWorld('now');
// or
use blueplanet as caprica;
$animal = new capricaAnimal();
$animal->saveTheWorld('now');

Why ?
namespace foo::bar;
function baz(){ echo "func";}
namespace foo;
class bar {
public static function baz() {
echo "method";
}
}
foo::bar::baz();

Still the Problem with MaC
keyboard
