Thanks!

FYI, some compilers actually have user flags to do that since that was the F90 semantics and not everybody was happy with the F2003 semantic change here.

For instance, gfortran has `-fno-realloc-lhs`, ifx has `-assume norealloc_lhs`, and nvfortran has `-Mallocatable=95`.

So we could also make that a  `-fno-realloc-lhs` user option.
