I'm guilty of that one. I often have something like this: 
if ($x == 1) {
    # do something
} elsif ($x == 2) {
    # do something else
} else {
    confess "should't be here!"
}

The idea is that I'm assuming that the subroutine got called with the right $x, but I leave that exception just in case.
