Not really, for instance the famous tree macro is short, and it take
ages to parse.
Parsing is not only reading the scene file, it's also creating the
memory representation of the scene.
If I were to agree with less text == less parsing, you have to remove
all
the comments, and all the blank lines (Wait, that's an idea, let's
remove
the carriage return/line feed : the one-line pov-scene !)

Exactly what I thought on the first post: you are asking for cosmetic
changes.

I would like the removal of sqrt(), instead you have to write
2^(1/2) (or 2**0.5 ?)
It's more like the formula in my math books. (fortran book ?)

It's just a cosmetic change.
Now, you can try to define a for() #macro for your personal usage.
something like:
#macro for(start,cond,inc,block)
start
#while(cond)
block
inc
#end
#end
Nota: I'm not sure this macro would ever work, or is even possible
Maybe it could be the real winner of the useless macro competition
(probably a higher complexity would help to gain some points...)
