That's not what I need.

_foo_2 () {
  emulate -L zsh
 _arguments '--one' '--two'

_foo_3 () {
  : different stuff

_foo_1 () {
  emulate -L ksh
  : do something

So now instead of simply doing 'emulate -L zsh' on the few functions
that I'm interested in, I have to shuffle around to code so that ksh
and zsh code doesn't mix together =/
