Innocently entering the fray :o).

1. I don't quite understand the sheer strength of opinion of Walter's in 
this particular matter. It's as if you chat with a friend and suddenly 
you figure he has a disproportionately strong opinion on some small 
matter. The argument is always the same invoking some 
so-bad-it's-painful-to-recount past experience. I do take the point but 
can't stop thinking I also have past experience to draw from that's not 
as traumatizing. Something that I did notice is very bad (and version 
awesomely avoids it) is the possibility to re#define macros in C such 
that the meaning of code depends on what has been sequentially 
read/included. But Boolean operators don't seem to have had a huge 
impact. So I'm always left a bit confused.

2. I have comparable difficulty understanding why the "opposition" feels 
also so strongly about it. There are various good means to approach 
versioning challenges without compromising. (Rikki's idea was new to me!)
