Lexer fails on dynamic object methods or fields

[cjohansson]

Like

<?php

$object = (object) array(
    'field_random' => 25
);
$field = 'random';
echo $object->{"field_$field"};

or

<?php
class MyClass { function myFunction() { return 'hello'; }}
$class = new MyClass();
$function = "Function";
echo $class->{"my$function"}();
