There are zillions of things we want to do at compile-time that will 
influence the way the library works (bounds checking, standards, 
pedanticity, and who-knows-what-other-userful-option). We will have to 
find a way to do that, although my first round of mails to this list to 
ask for suggestions for this didn't really seem to raise interest.

I am just wondering whether the same framework could be put up for 
link-time selections. There are many ways to do that, avoiding the 
duplication (and then, "quadriplation", "octuplation" ;-) of size.
