The return builtin is currently specified only for shell functions
and "." scripts, while it would also be useful to end a script,
for instance to be able to use zsh script both as commands (e.g.
from non-zsh shells) and as autoloaded functions in zsh.

So I think that it would be useful to extend it to end a script.
