So your answers are: no and yes in that order? If so, why don't you just 
tell him that and perhaps explain when to use and not to use macros and 
functions? This is povray.newusers you know.

Anyway, there is apparently a feeling on what would be a logical 
approach. There may be reasons why it is hard to implement now. Yet, 
this kind of information is very important when designing POV4. If you 
had though about it, you would have realized that povray.newusers is a 
goldmine to find out how to change SDL4 to be more in line of what 
'naive' people are expecting.

I know your style and I realise that you probably do not mean to sound 
so arrogant and hostile. Newusers on the other hand may be scared away 
from asking questions because of you. Even though most people here are 
actually very friendly and helpful.
