Survive a loop

Problem

Loop over the numbers 1, 2, and 3. For each number, print ok: <n>, except that when the number is 2 you should die "bad: 2". Add a CATCH phaser inside the loop body that prints caught: <message>, so that one bad iteration does not stop the whole loop.

Example

The program prints:

ok: 1
caught: bad: 2
ok: 3
