This is it in one. Now seeing as you guys are the experts, does inheriting off
something observe that something's friend rules? ie; does the class begin before
inheriting or after?
I should add I tested against v3.2 where it does work, not v3.3 which dies with
certain code sequences in my code so I tend to avoid it (v3.4 has them fixed so
I haven't reported these).
Cheers,
Niall
