$? being clobbered?

[Phil!Gregory <phil_g@xxxxxxxxx>]

I'm having a problem with zsh, and am not sure if it's a bug or a
feature.  If I have a program executed in my prompt, its return status
clobbers the value of $?, which isn't really what I want.  Example:

> PROMPT='> '
> perl -e 'exit 42'
> echo $?
42
> PROMPT='%{$(echoti cub 80)%}> '
> perl -e 'exit 42'
> echo $?
0

Is there some way to fix this?

(zsh 4.0.7, Sven.)
