That's sort of the point -- there's nothing that compels us, hence ...

} How do you think that option should affect this?

To be pedantic, I didn't say I think that; I said I could understand how
one might argue that position.  To try to frame it -- the implication is
that a trap created under LOCAL_TRAPS should *never* alter traps in any
outer scope.  This ought to include the global scope, regardless of the
context in which the global trap was created.

I.e. given "setopt POSIX_TRAPS LOCAL_TRAPS" this argues that LOCAL_TRAPS
should "win".  With PWS's patch, POSIX_TRAPS prevails.
