Also I suspect that the change from boost::is_same to std::is_same is going to break a lot of code, unless the mpl tag requiremnet is lifted ;-)
Ditto.
The boost type_traits integral constant is derived from mpl::integral_c which has a tag type member, without which boost:::integral_constant wouldnt work with mpl types such as equal_to. The std version doesnt specify the tag, nor does the boost type_traits version in its documentation. Without the tag, boost::integral_constant would not work with mpl types such as equal_to as demonstrated in another mail in this thread. Therefore changing from boost::integral_constant to std::integral_constant will break code that uses mpl. Maybe its not important, but the innocent std:: integral_constant will appear to be bug ridden. regards Andy Little
