Variables in LDraw files

[Max Murtazin]

I am pretty sure the answer is "no, no, not ever, no thanks, that is a terrible idea" BUT I wanted to ask if there is support for variables in the LDraw file format? 

It would probably take support of all the editors and renders which is probably causing someone's eyebrows to make odd shapes as even type this out  

I am someone who enjoys the "make it once and for all use cases", so the pragmatic nature of making a lot of similar parts that have one or two changes for each iteration feels quite bothersome.

I'm not sure how this can be useful, any examples?
