This typo generates an error...

perl -le 'BAR: print 1; BAZ: for (2..3) {print; redo BAR; }'
[download]

This typo causes an infinite loop...

perl -le 'BAR: print 1; BAZ: for (2..3) {print; goto BAR; }'
[download]

That's a pretty weak example, because if you omit the typos, both

perl -le 'BAR: print 1; BAZ: for (2..3) {print; redo BAZ; }'
[download]

and

perl -le 'BAR: print 1; BAZ: for (2..3) {print; goto BAZ; }'
[download]

behave identically - looping infinitely.
