It's a good technique when you have optional arguments to pass to a sub, or you have more than three or four. Look at the constructor for any of the IO:: modules, for example, or (as has been stated) just about anything in CGI.pm.

Don't overlook the ability to provide default arguments as well. This isn't always appropriate, but there are times when it handily beats @_ and shift.
