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.
