Ok. I, OTOH, really likes that kind of notation, since I write a lot of 
GLSL as well.

The point I'm trying to make is that there is as almost much opinion on 
member-access on vectors as there are on code indent size. So, whatever 
we make ought to support everything, if we want it to be acceptable to a 
large audience?

Perhaps we can make it so that you can decouple access style from the 
general algorithms? We might need that anyway, if we want to support 
things like rgba, stqr, etc, for the small 1-4 element vectors.
