As Martin Dobias asked me, I updated my code and implemented Spatial Operator in QgsExpression as NodeFunction.<br>
You can review the code here :<br>

<br></blockquote><div><br></div><div>Thanks for the update. I went through the code and things look good. I have only one concern: QgsGeometry instances stored in QVariant do not seem to be released... When "$geometry" is used, then it's returning the instance from the feature (which should not be deleted), but temporary geometries constructed from wkt/gml must be deleted.</div>
<div><br></div><div>Maybe we should store directly QgsGeometry object instead of just a pointer inside?</div><div><br></div><div>Regards</div><div>Martin</div><div><br></div></div></div>
