(at least in MSVC) then it inherits directly from boost::mpl::list, instead of inheriting from the individual members of the list. Is there a way to make it inherit from each type in the list instead? inherit_linearly appears to accept anything modelling the ForwardSequence concept as its template argument, so it seems like inherit should do the same unless I'm just missing something.

mpl::inherit is a simple metafunction that inherits from all its arguments. mpl::inherit_linearly is a thin wrapper around mpl::fold. In Christ, Steven Watanabe
