Re: [eigen] Inheritence

I think even that example is not perfect. Constructors are not inherited, so you will need to re-declare any constructors you want also. You probably want at least the copy constructor from an arbitrary Eigen matrix type. And operator= is more easily defined with a using statement if you do not need additional behavior from it. I wrote up an example at http://www.ros.org/wiki/eigen#Creating_typedefs_for_Eigen_types for a coworker who wanted something like a "templated typedef" over Eigen types. The inheritance approach as you can see is pretty complicated to get right.

Usual caveats about inheriting from STL containers also apply, see for example this thread: http://www.phwinfo.com/forum/comp-lang-cplus/333672-avoid-inheritance-std-map.html
