Right. This was my initial idea; the else/otherwise stuff is too confusing as
it hints too strongly to if blocks. So
loop { ... } or print "Sorry\n";
loop {
...
}
or {
print "Sorry\n";
# do other stuff
}
loop { ... } and print "Done\n";
The point is that it gives you the option to easily do something after the
loop with the knowledge of whether the loop failed or succeeded, and it makes
more grammatical sense, too. (loop/else doesn't.)
