I heard about this recently too. All to avoid the design error of not allowing multiple inheritance, along with other design errors of not having a proper OOP system such as Python's, Ruby's, Perl's, or CLOS. I work with PHP pretty frequently and I like the language for what it does well, I might even use Traits when 5.4 is the new 5.2, I just can't get excited about features other languages have had for a long time. (I guess I've become a Lisp snob or something even though I don't use Lisp all that often.
