It is possible to define that NULL is a valid entry in an array and we would stick to the same decision as for actual parameters, namely that one has to define explicitly that null is a valid entry. This would make me happy and I suppose also Philip. Just as side notice, this syntax would also give the chance for PHP to get rid of the double meaning of "=null" in a later version. I am talking about the following case: function foo(Foo $a=null, $b=1){} Where one might not want to specify that $a is optional but cannot do it differently at the moment - with the additional ? it could change :)
