I think that someone was me.

This doesn't actually bother me.  It's happened with the safe numerics 
library and it hasn't created a problem - at least in my tests and examples.

I suggested this idea without really thinking it through. Hmmm - not an 
uncommon occurrence.  I see now that it would require a totally new 
library based on tuple rather than on vector.
