"next LABEL" and/or "last LABEL" constructions ... somewhere(!) anywhere(!!) else ... Code such as this is quite possibly worse than a GOTO. Again, that's FUD, and "anywhere" is plain wrong. If one sees either a label on a loop/block or `next/last/redo LABEL`, then that label is quickly found via a search, and unlike `goto`, one knows which scope the label has to be in ("`Exiting subroutine via next/last`" are important warnings).
