Templates are initiated by the compiler based on what is available.  This
fails as nobody wrote one with this 'const' signature.  Now, if you want and
need it, maybe you could supply it?

The nice thing is that you can even do this locally first and test, and, if
you're so inclined, contribute it as a patch to RcppEigen later.
