Programmers are lazy. Telling someone “you need to setup an atexit handler that
calls xo_finish” will be met with teeth gnashing and complaints (I’ve had to
deal with a bunch of people who complain that FreeBSD is not Linux at $work; I
don’t have any interest in fighting developers over stuff like this).

Yes, but there’s a big difference between a typo in !libxo with the meta
language, and a typo in libxo. Typo in !libxo: typos visible, unless it was
something silly like mis-spelling \n (which doesn’t seem to happen much); typo
in libxo: xo_emit call is invalid (no output)/segfaults.
Fortunately libxo seems to support __printflike :).
