Hi

Why not something more generic.
Someone could think of a ValueNode.

Then it could be use for object, array, any primitive type ...

I will take the ValueNode as a non terminal grammar node.
So first we could do that:

ValueNode->method();
ValueNode::sMethod();
ValueNode[];
foo(ValueNode);
echo ValueNode;
$e = ValueNode;
...

And a ValueNode could be define as:

ValueNode :

       NewStatement
     | FunctionCall
     | PrimitiveValue
     | '(' ValueNode ')'
     | ...;

This would allow all this syntax:

(new A())->foo();
foo(new A());
foo->bar()[1];
foo()[5];

and many others.
