  This is exactly what I meant.

  I don't think it's a very good idea to hurry too much. I know that the
idea of making a POV-Ray patch is exciting, but in the long run too much
hurry causes more problems than it's worth.
  If the goal is to learn programming, there are much better ways of doing
it than go straight to POV-Ray source code and try to understand it. POV-Ray
is huge and made by many people and it uses very complicated algorithms
which are not easy to understand. Trying to deal with all this in a state
where you are still trying to remember how to write a function can be just
too much.

  Of course you can try if you want. Who am I to stop you anyways? I'm just
trying to give advice based on my own experience.
