Variables in LDraw files

[Cam's Bricks]

While this is a good idea, it would break backwards compatibility in a huge way.

In my (long neglected) LPov project, I created a POV-Ray macro to programmatically create plates and bricks in much the same way as you describe above.

I am not asking to change anything. I am glad I am not the only one to have thought of this. 

I was more or less doing a check to make sure there wasnt some hidden feature to do this kind of programing in the files before I do it outside the ldraw format and then export to dat.
