[SciPy-Dev] least squares solvers

Why is the non-linear LS solver in sp.optimize called leastsq, whereas the linear solver in sp.linalg is called lstsq? Wouldn't a consistent name be better? sp.linalg.lstsq uses SVD, by lapack driver *gelss. If we don't need singular values, solving by QR is faster (lapack driver *gels). (I actually use Fortran just to get DGELS instead of DGELSS.) Sturla
