We probably want to defeat TRAPZERR within the new
completion stuff. Mine just prints "That didn't work",
which isn't desirable during completion.
I'm not sure about the other special functions.

You can do
zsh% eval newname "$(functions oldname)"
zsh% oldname() { ... }
zsh% eval oldname "$(functions newname)"
zsh% unfunction newname
as long as newname is unique and oldname isn't awaiting autoload.
For traps, if you use the "trap" builtin instead of a TRAPxxx() function,
the trap is automatically removed at the end of the local scope. That
does not restore any outer-scope traps, though (global-scope TRAPxxx() is
deleted by local-scope "trap ... xxx" commands).

Hmm, I thought Functions/Complete/_main_complete was the main
completion function. Where is it?
As far as restoring it, Do'h! I thought I tested that, but obviously
not. Is there an easy way to bind a function to a different name and
restore it? I've tried games with stuff like foo=$(functions TRAPZERR)

Possibly so, but it ought to be done on entry into the main completion
function and undone again before returning.
