Good, it seems to be fairly portable. I was surprised, last year (?),
to learn that new compiler versions sometimes can't compile the code,
but from the comments I received it seems that this is "normal" and
happens for any advanced templated C++ code. It still seems strange to
me, but I won't discuss C++ specifics.

It looks good, but only if the unit tests are kept unchanged across
successive versions (does Eigen 3.2 pass the unit tests of Eigen 3.0
and 3.1?). The underlying question is how long will code written for
Eigen 3.2 be usable with the latest maintained version of Eigen. I'd
like to see a statement like the one by GSL people[1] on the Eigen
website. I'll ask specific questions about that on the eigen
mailing-list, and bring this info here.

[1] "GSL is a mature library with a stable API. The main emphasis is
on ensuring the stability of the existing functions, tidying up and
fixing any bugs that are reported."
