I agree with choroba, and just wanted to add that additionally I might consider it acceptable in a longer script to use local @ARGV in a small scope (keeping in mind that this is dynamic scoping, so any function called from within that block will also see the localized values). One neat trick is to combine this with with $^I to do inplace editing of files, like with the -i switch:

$ perl -i -ple '$_.="\n" if $. % 4 == 0; close ARGV if eof' -- FILES

Becomes:

{ # new scope for local
    local *ARGV; @ARGV = @files;
    local $^I = ""; # -i command line switch
    while (<>) {
        print $_;
        print "\n" if $. % 4 == 0;
        close ARGV if eof;
    }
}

Update: Fixed this potential issue in the above example code.
