Matching one array against another

[scott lutz]

I have a question that to me seems like it would be part of the foundation 
of Perl.

@possible_matches = qw( list of items to match against  );


@list = qw(     imagine that there is an unknown
                number of elements in here      );

foreach $list (@list) {
        # now match againt each value in @possible_matches, one-by-one,
}

Is this not possible?
