This is some very cool stuff!

However, the way I understand it, inherit_linearly takes a type sequence
(like mpl::list) as an argument and inherit takes the types themselves
as arguments. I'd like to have an inherit that takes a type sequence as
an argument, instead of or in addition to the current inherit. This is
because I need to do some Modern-C++-Design-ish stuff which needs a
scattered hierarchy instead of a linear one.
