You forgot the 'Segmentation Fault' at the last line

It is on the list, but was never written to stdout because of a NULL pointer exception.

Bounds checking as separate from off-by-one just means you stop using C arrays. That's not hard. And why point at callbacks specifically? And scope creep is not a computer science problem; it's easy to avoid if people decide to avoid it.

So this list is too bloated for the joke to work well, I think. Even before we talk about how off-by-one gets ruined this way.

Haven't seen that variant before! Thanks.

asynchronous callbacks are more of "wrong solution" than hard problem...
