This brings up something that's been on the tip of my toungue for awhile. In many object-oriented languages we have seen that there is an important difference between "equal" and "same." Perl already has two kinds of equal, but IIRC there is nothing to test whether two variables refer to the same place in memory. Should there be? Luke
