Depends whether you follow Damian Conway's PBP strictly :)

At $work, we mostly do follow PBP, but with some exceptions - avoiding unless 
is one of the bits we ignore when it makes code clearer.

In this case, however, we're talking bits of code for people who are just 
learning Perl, and "unless" might be somewhat new to them still; if they're 
coming from another language, "if" is probably going to be more familiar and 
easier to mentally parse, I'd imagine.
