#r_void ⇒ Object

This is not exactly how compile/render is meant to work with Parser, but there is no real need for a two step rendering, so we compile here (enter(:void)) instead of doing this whith ‘start’. This also lets us have the context during compilation which makes it easier to manage the callbacks to the helper.
