Robert; Is this because Boros is a forward reference? And is this not a bug?
Actually I'm quite surprised you got the second version to compile at all. You are defining a chicken as something that comes out of a egg, while a egg is something that comes out of a chicken. On behalf of your cpu and ram I suggest you stop doing this; if every Ouro contains a Boros (which in turn contains a Ouro (which in turn contains a Boros (which in turn contains a Ouro (which in turn contains a Boros (which in turn contains a Ouro (which in turn contains a Boros (which in turn contains a Ouro (which in turn contains a Boros(which in turn contains a Ouro (which in turn contains a Boros (which in turn contains a Ouro (which in turn contains a Boros ( and so on )))))))))))) then there will be trouble. Yours, Kas.
