I think I am. I meant:
function exit_and_foo {
function TRAPEXIT { exec foo }
exit
}
defined and then just call exit_and_foo.

That's what Misc/c2z is for.

Well, there's no harm in being explicit (this patch is a
replacement).

The exit trap isn't run before an exec, for just the same reason that
.zlogout isn't, i.e. the shell isn't exiting, it's overlaying a
process without forking first. I should think the only thing you can
do is hook into exec itself by an alias or function. But the securer
you want to be, the better it probably is just to call whatever
explicitly before the exec. Unless you're saying something slightly
different to what I've understood.

Does a reminder about the effect of exec belong in the manual or the
FAQ? I've had to sort out problems for a few people (normally
.bash_logout rather than .zlogout) where they just hadn't thought
through that using exec foobar would stop the shell sourcing the logout
scripts.
For those who really want maintenance logs or whatever, but still want
to exec something (an interruptible secure program), I usually suggest a
function/alias that does a TRAPEXIT/trap '' 0 -- is this really the
best idea?

Just to mention, that .zlogout is listed in FILES section in manual, but
never mentioned anywhere in text. In particular, I don't know, if .zlogout
is _always_ excuted when shell exits (e.g. HUP) or only when exiting with
exit/logout command. Or only logout?
BTW if zsh is started as csh, are csh-specific files (.login, .cshrc,
.logout) executed?

This is a strange omission. It's executed any time a login shell
exits (unless it crashes, obviously). I hope the patch makes it clear
enough.

No, because the syntax is do different to have any hope of this
working.
