Hi, all. I ran across some code in "Practical Perl Programming" that will solve several problems for me. I also am aware of the Alias module on CPAN, but wanted to see if I could get this working first. Below is a snippet. 
package Foo;
use strict;

sub Test
{
    my @a = (1,2,3);
    my $aref = \@a;

    local (*aa) = $aref;
    
    push (@aa, 4); # line 11
    print "aa:",join(",",@aa),"\n"; # line 12
}

Test ();

Why must I qualify uses of aa as in Foo::aa? If I don't I get the error "Variable @aa not imported at xxx line yyy". By the way, having to qualify all the uses of aa is what I'm trying to avoid.
