No, just eval, which is a peculiar case because you really don't know
what it's going to do.  The workaround I gave (assignment after the
eval) is really the best way of doing it.  You can certainly argue
it's not right to have eval as a special case, but I'd say exporting
it rather than just setting it is the safest here.

This is supposed to depend on the setting of POSIXBUILTINS.  It does
seem to work for me.  It's annoying there's yet another option, but I
think it's mainly for setting for for ksh emulation rather than `real'
zsh users.

Possibly the patch I sent should have a !isset(POSIXBUILTINS) wrapper?
