Closures inside classes cannot acces their private methods dynamically

[roberthusak]

The reason for this is the missing type context of such call site (related to #96). See the following test case:

<?php
class A {
  private function foo() {
    echo "foo";
  }

  public function bar($method) {
    $fn = function() use ($method) {
      $this->$method();
    };
    $fn();
  }
}

(new A)->bar('foo');

Expected result: foo Actual result: 'foo' not found
