how do I find if at least one of many keys in a list is in a hash (quick, fast, and simple)

Dunno if this meets *all* of your criteria, but I find this simple enough: 

my @search_keys = qw(one two three);
my %hash = ( four=>4,
         five=>5,
        six=>6);
my $foundit =0;
foreach (@search_keys) {
    if (exists $hash{$_}) {
        $foundit =1;
        print "found an entry for $_ in %hash!\n";
        }
}
