Or the opposite.
For example if one want to access to a matrix without control, has to use the coeff() or coeffRef() 
methods, while the operator() (i.e. the primary choice) makes a control. In order to ensure the 
consistency with the other parts of Eigen, the solve() method should make a control, while another 
method (solveWithoutCheck() or whatever) should return the solution without performing the check.
