It would be nice if there were a proxy class doing this for me.
E.g. within my own (dated) matrix/vector class I had proxy classes
Vector_L and Matrix_L which were used as return values and which can be
passed as const reference. All write-access operators, like operator[],
operator>> and operator== do const casting internally.
Basically this would be a Block<MatrixType, Dynamik, 1> in your case,
however you could not pass a normal VectorXi to your method then,
because there is no implicit cast to a templated type, iirc.
Maybe something can be worked out, if bug 58 is worked on someday:

I started working on a proposal once, but unfortunately never find time
to finish :(
