The only time unless should ever be used is in postfix notation, as in: die "No arguments passed in!" unless @_; Otherwise, unless is bulky, a waste of space, confusing to new Perl programmers, and unscalable. (As soon as you add an 'else' clause, people have to read it two or three times to understand what's being done). Avoid at all costs.
