You probably want
method TOP($/) { make GA.new }
The 'make' builtin works on its caller's $/ variable, and
in the version of TOP given above there's no $/ variable
set. More precisely, the $/ for TOP is undef, and that's
why you're getting the "result_object" not found message.
As mentioned on irc/#perl6, a more helpful error message
might be useful here, so we'll leave this ticket open for
that (and change the topic appropriately).
Thanks for reporting!
