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.

Hi Tig

Would be at all possible to implement this kind of shortcut?
Its called array-dereferencing and it was proposed countless times,
including by myself. There is an RFC for this[1] and it was planned on
the old PHP6 todo at the PDT[2].

Not an expert in this area, but does this mechanism limit you to using
single dimensional arrays?
Of course not as soon as you add array access to a ValueNode
ValueNode
..
| ArrayAccess
...;
This is very simple and it can refactor greatly the parser.
