[Boost-users] [type_traits] ice_or / ice_and not documented but recommended in coding guidelines

Hi, I have a concern about the usage of boost::type_traits::ice_or and boost::type_traits::ice_and. I've seen it used in many places and it's even recommented in Coding Guidelines for Integral Constant Expressions [1]. The question is: why isn't it documented? Is there any reason for it? Is there any "public" (documented) equivalent? WBR, Adam Romanek [1] - http://www.boost.org/development/int_const_guidelines.html
