Sorry, I realise I wrote the opposite of what I meant.

What I meant was that instead of introducing a  cumbersome
confusing syntax, We could get rid of "emulate" (yes the
contrary of what I actually wrote) and do it with setopt.

Instead of "emulate zsh", do "setopt $zsh_options", and instead of 
"emulate -L zsh", "setopt localoptions $zsh_options", where
$zsh_options is a special parameters that contains the option
settings needed to /emulate/ zsh.

What do you think?
