Pickyness question

[Christopher H. Laco]

Just because I'm like that. :-)
I noticed in A-T/t/redirect.t we have:
        plan tests => 6, need_module('mod_alias.c') && &need_lwp;
Of course, I noticed this after skimming over the A-T pod again , where 
it mentions:

        It's also important to mention to avoid using:
                plan tests => 1, requirement1 && requirement2;
For that matter, sometimes I see:
        plan tests -> 1, need_lwp;
        plan tests -> 1, &need_lwp;
        plan tests -> 1, \&need_lwp;
From a pure A-T coding standpoint, which is preferred?
