S12 will be a big help here. You may have found it already. <http://perlcabal.org/syn/S12.html> I include a few quick pointers below, which also may help. > - class Tree { ... } Perl 6 doesn't like types it hasn't seen yet. Because Tree::Branch uses Tree, I need to declare Tree before I define it. The dots '...' say "implementation forthcoming, but there's a type called 'Tree'". > - handles <left right>;, It's delegation. Instead of writing 'method left { $.branch.left }' in that class, I just say that $.branch handles calls to 'left'. > - self.bless(*,, etc.) Any 'self.bless' you see means "create a new instance of this class, with these attributes set". // Carl
