If there isn't an appropriate, simple way to do this I'm going to be very surprised.

You can do it pretty easily with package variables:

@array1 = 0..9;
*array2 = *array1;

pop @array1;
print "@array2\n";

pop @array2;
print "@array1\n"

But I think the flaming death risk is pretty high here, too, though for different reasons.

Update: you can also use a similar technique to alias to a reference, though again the alias is a package variable, and as such carries all the associated caveats. Example:

sub foo {
    my ($ref) = @_;
    local *nonref = $ref;

    pop @nonref;
    print "@$ref\n";

    pop @$ref;
    print "@nonref\n";
}

foo([ 0 .. 9 ]);
