[boost] optimization of boost::end

The common idiom is:

for (; i != boost::end (vector); ++i) ...

The compiler had damn well better realize that boost::end is a constant
function that can be lifted from the loop, or performance can be severely
impacted.

Does anyone have any experience with this?  Is there a portable way to give
hints to the compiler?  Should boost provide such a facility?
