Yes, thx. In general I would have like to compare the current boost
implementation with blaze and eigen.
I think there are several features or also neglect which we might add to

- Should we integrate smart expression templates? I think there was a gsoc
project but I am not sure. What was the output?
- Are (smart) expression templates really required?
- How often do expressions like A = B*C + D*D - ... occur in numerical
- Should we provide a fast gemm implementation of the Goto-Algorithm like
in Eigen?

And regarding the code infrastructure:

- Do we need iterators within matrix and vector template classes? Or can we
generalize the concepts?
- Can we maybe simplify/replace the projection function with overloaded

General questions:

- Shall we build uBLAS a high-performance library?
- Could it also be a convenient wrapper library with good interfaces to
high-performance libraries such as OpenBLAS?
