Suppose I have a class, and I want to have a persistent tie to a dbm file. I'm using strict also. I want to have two subs, a connect and disconnect. If I were to do 
sub connect {
     my $self = shift;
     tie %data, "AnyDBM_File", "data", O_RDWR, 0644
          or die "Cannot open data for read.\n";
     return 1;
}

sub disconnect {
     untie %data;
}

Would it work the way I'd hope it would? Or would the tie to data be lost because of the scope of the sub? Could I then do something like 
sub data {
     my $self = shift;
     my $bar = shift;

     if(@_) {
          $data{$bar} = $self->{FOO};
     }
}

And expect it to behave correctly? Perhaps it would be better to tie the dbm file to a class member, but I don't know how one would do that.
