The purpose of RFCs is to improve the current PHP5 object model.

Actual PHP5 object model provides the basic for Object Oriented programming but it lacks for support for library or third parties developers.

• Provide a default empty constructor (if applicable)
• Remove the inheritance
• Disallow directly calls to them
• Ensure constructor call on parent classes

• disallow directly call from outer context?
• markers interfaces

• provide a magic constant with the fully qualified class name

namespace Foo {
	class Baz {} 
}
namespace Test { 
	use \Foo\Baz;
 
	interface Marker {}
	class Bar implements Marker {}
 
	var_dump( Marker::CLASS );	// string "Test\Marker"
	var_dump( Baz::CLASS );		// string "Foo\Baz"
	var_dump( Bar::CLASS );		// string "Test\Bar"
}
 

• Improve PHP Exception class
• Remove errors/warnings, throw an Exceptions instead
• Better stacks dump

try {
	include $file; // as of today we just die here
} catch(Exception $e) {
	echo $e->getMessage();
	throw new DomainException($e);
}
