Ok, thanks dude. So if I have my code do this:
$self-> = \@users;
how do I pull the data out again later when I need it?
I've tried:
my @users = ref $self->; //same message as above
my @users = @$self->;
my @users = $self->;
my @users = map $self->; //gave 500 internal server err
my @users = ( $self-> ); //same as original err
my @users = scalar $self->;
I have no idea what the hell I'm doing or what any of these keywords
mean. All I want to do is pull that array back into a variable. Anyone?
