All the value based traits in this library conform to MPL's requirements for an Integral Constant type: that includes a number of rather intrusive workarounds for broken compilers.
Purely as an implementation detail, this means that true_type
inherits from boost::mpl::true_,
false_type
inherits from boost::mpl::false_,
and integral_constant<T,
v>
inherits from boost::mpl::integral_c<T,v>
(provided T is not bool)
