But POSIX is irrelevant to function-local traps because they are not
defined in POSIX, so, once emulation mode is exited, there is nothing
that compels you to make them wipe out a global POSIX trap.

I think it would actually be more consistent with the intention of the
POSIX trap if it survived a function-local native zsh trap; the
intention of the POSIX trap was for it to be executed on program exit,
so having it wiped out by a temporary function-local trap doesn't seem
helpful.

How do you think that option should affect this?
