• Merlyn strongly suggested that I unify the behavior of new() for named
  classes and un-named objects. After much discussion, I concurred. This
  is a BACKWARDS INCOMPATIBLE change. Hopefully it will not affect too
  much code. In 1.01, calling new() on an un-named object was identical
  to calling Class::Prototyped->new(). In 1.10, calling new() on an
  un-named object ALSO adds 'class*' as a slot pointing to the original
  object. This also necessitated a change to clone.
  
• Two new Class::Prototyped methods are added: clonePackage (a cross between
  clone and newPackage) and newCore (implements core object instantiation
  behavior). If you implement either method in any of your Class::Prototyped
  code, there will be problems!
  
• Fixed a bug in Class::Prototyped::Mirror::Normal::new that affected
  superable calls to C::P objects following reflection on a non-C::P object
  blessed into a C::P class.
