There is one frequent case where goto could be tempting: exiting nested loops or
if blocks.

It would be very useful, and not very difficult, to implement an "exit n" or
"exit <loop_label" or exif for if blocks. This would be a valuable addition,
without any new keyword.

Of course (as for goto targets), the values must be constants. Otherwise, it
becomes very difficult, as Bernie pointed out.
