Traits vs. Grafts in PHP6
would After today's release of PHP 5.3
I do something about two potential implementations that could change the object-oriented paradigm in PHP6 fundamental report. Tuesday, June 30, 2009
Diamond problem

trait is still the state of the object-oriented programming technology, as it tries to rule out problems at the design.

trait A {public function print () {echo 'A &';}} trait B {public function print () {echo 'B!';}} trait AandB {use A, B;}
class MyClass {use AandB;}
use MyGraft { public bar () from foo ();}class MyGraft {public function foo () {echo 'foo';}}
A graft is, as far as I know, novel concept that so far has been implemented in any programming language. A graft is a class that the previous within their class definition to at least two defined classes falls back, and defines the scope in the class definition explicitly:
class MyGraftedClass {use MyGraft {public foo ();}
}
A graft extends thus from the existing, independent base classes, the methods to be used again out, and sets in the new class a new, artificial namespace the properties of the source classes copied. By name duplication, the order of hineinge-grafta bad OOP design seduced. It is a compromise that attempts to the problems that can generate multiple inheritance to dampen. A Interface respectively.

I think that a graft
Spiritual proposals on this exciting topic, it is here . I hope and I would imagine that the concept of graft loss due to conceptual errors and the unfamiliarity of the immense struggle to use the programming concept.
