To be consistent with the Matrix, GenericMatrix (++) design already in
Dolfin one could have: 

class GenericSolver {
	virtual uint solve(const GenericPreconditioner& B, 
                           const GenericMatrix& A, 
                                 GenericVector& x, 
                           const GenericVector& b) = 0;
}; 

And the corresponding: 

class   Solver {
	virtual uint solve(const Preconditioner& B, 
                           const Matrix& A, 
                                 Vector& x, 
                           const Vector& b) 

{
                           solver->solve(B,A,x,b); 
}
};
