unfortunately, ElegantBeef's reply did not really convince me.
it's good to know the use of `-d:danger` and `--checks:off` with this scenario.
i tried compile a snippet with `--checks:off`, the output surprised me:
`deque.popLast()` always returns `0`; does that make sense? there is no
document describes this behavior.
proc test_deque =
var x = [1].toDeque
echo "1: ", x.popLast
try:
echo "2: ", x.popLast
echo "3: ", x.popLast
echo "4: ", x.popLast
except IndexError:
echo "catched IndexError"
when isMainModule:
test_deque()
Run
in the end, i think that behavior is a good reason to keep away from `EAFP` in
nim.
