I was having trouble coming up with an example last night, but:

You may have noticed that "noglob" acts a bit like "command" in that
aliases are not expanded:

% alias foo='echo you typed'
% noglob foo *
zsh: command not found: foo

So suppose you want aliases expanded after noglob.  To do that, you

% alias noglob='noglob '

(with the trailing space in the quotes).  Now:

% noglob foo *
you typed *

However, if you have

% alias zmv='() { . zmv }'
% noglob zmv
% functions
noglob () {
        . zmv

It's very unlikely this would happen because you'd probably put some
arguments after zmv and get a parse error, but if you replace () with
"function" then you get the parse error every time and no accidents.

If you want noglob with zmv you have to autoload the real function, as
there's no way to use precommand modifiers with an anonymous function.
