in reply to references to arrays. I don't really get it I guess...

The "Not an ARRAY ref" error is due to precendence rules. Consider: 
print "@{$self->{array}}";
vs
print "@$self->{array}";

That said - there are a number of other problems with your code that will show up once you "use strict;".

    Thanks. The braces makes a lot of sense. The thing was in my real code I still got errors when I used braces. But this was actually from another iteration where $self was a different thing altogether but the error looked the same so I assumed it was. Uh, what sort of "number of other problems". Might as well find out about them now rather than later.

      Why don't you "use strict;" and find out?

      The first problem is your @gum array. You initialize it in package "main", but you reference it in package "test". Which means that you are accessing two different @gum arrays: @main::gum and @test::gum. Using "strict" would point that out (among other things).
