Hi guys, Just wanted to provide some closure to the subject, the Eigen developers provided me with a workaround that allows to store expression template operands by value instead of by reference, and they in fact opened a bug to better support the use case I brought up at: http://eigen.tuxfamily.org/bz/show_bug.cgi?id=99 Eric, I am also following your suggestion to use transforms, since right now I'm mixing proto::eval and some transforms, but as I finally understand transforms a little better, it seems they can simplify my code quite a lot in this case.
