The combination of multiple inheritance and generic programming using
templates is described in the book

Andrei Alexandrescu (2001) Modern C++ Design.

and is called  "Policy-Based Design" there.

As far as I know, mixing multiple inheritance with meta programming
techniques in general and Policy-Based Design in particular is not a
major trend in boost (others may correct me, if I'm wrong).

More dominant are designs using static polymorphism via
metaprogramming without (multiple) inheritance based on the notion of
"concepts". Such designs are working similar to the approach described
in

Jaakko Järvi, et.al: Concept-Controlled Polymorphism
