mpl::list is just a dot-style typelist with a interface-simplifying wrapper
on top. I am fairly certain that there is little or no overhead due to the
structure of mpl::list itself. Rather, I think the generality of the
algorithm implementations tend to make them slower than neccessary when
applied to type lists. This can be solved as similar problems are solved in
STL, by specializing the algorithms to operate efficiently on the target
structures.
