This is the second time in recent days that I have seen use warnings suggested to someone whose code already included #!/usr/bin/perl -w. I have long been under the impression that the -w switch is equivalent to use warnings. (man perlrun states that -w "prints warnings about dubious constructs" and "really just enables the internal $^W variable", but does not explictly describe its relation to use warnings.)

Is there an actual, functional difference between the two? If not, why the suggestion that both should be used?
