Salut,

General Comment: 
Before accpeting Multi-array I would like
to have a discussion on the integration of 
Multi-Array / MTLv3 / ublas. We should avoid ending up
with 3 unrelated  Matrix packages.

I'd also interested to see such comparisons. It's important
for those who have to apply for supercomputer grants.

I agree.
