I just checked in Rose::HTML::Objects 0.605_04 (revision 2024) which
contains some significant internal changes to inheritance in an effort
to fix mro c3 class hierarchy errors and generally simplify the
inheritance process and tree within the module. Please test this new
version with your code and let me know if it breaks anything. If I
don't hear any complaints, this change will go out as part of the
0.606 release in a week or so.
