I would welcome Fortran-style end- and loop-labeling. Emacs' F90 mode inserts these labels for you automatically on the corresponding end statements if you had previously included them on the opening do, function, subroutine, module, etc., statement. The ability to concisely, clearly, and efficiently exit from a deeply nested loop structure is very powerful and useful.
