Objects are not converted to strings (e.g. using __toString())

[vdboor]

When a VariableNode() resolves an object, it is not printed as string.
This could be done using the __toString() method.

Where could this be implemented?
The source was a bit unclear for me, whether that needs to happen in resolve(), getVariable() or escape()

I would recommend fork h2o, then add additional logic in Context#resolve before the return value before the applyFilters

  function resolve($var) {
  ....

  if (is_object($result)) {
        // check existence of __toString on the class definition then overwrite $result
  }

  $result = $this->applyFilters($result,$filters);
    return $result;
}
