another example
i think we agreed that a 'symmetry' concept must be handled
and as i suppose a symmetric matrix is always square how you would
handle such illegal attempts?

    matrix<double, settings( symmetric ) > m;
    m.resize( ofSize(6,7) );

(i just thought: maybe restricting to 'm.resize( ofSize(6) );' ?)
