Hi, 
	I was thinking -> too.. Had ideas of namespaces being object instances in their own right..

namespace foo { const ACONST = '1'; class bar {} } 

echo $foo->bar;			// some mangled internal class name (foo_bar_123 or something) to make it unique
$a = new $foo->bar();			
$ref = new ReflectionClass($foo->bar);
