You didn't posted a single example that wasn't optimized by LLVM. 
I do understand that some compiler may not do the optimization, 
but it is show already that this is clearly possible and in fact 
done. That is not an theoretical improvement.

I don't see the point in creating a new type of range simply 
because some compiler don't optimize properly.
