* Hopefully the last big naming change: Instead of writing "C class-object method foo {} {...}" one can write now "C class method foo {} {...}" to define a class method named "foo" for class "C". This naming change became possible by defining XOTcl's "class" (and "superclass") as object parameter only. To change a class of an object o, one has to use "o configure -class NEWCLASS". The term "object-class" looks alien to language beginners, the term "class" is much more straightforward. Changing classes or superclasses is seldomly used by typicall application programs. For already existing nx scripts, changing "object-class" into class should be straightforward.
* various documentation updates (migration guide, nx tutorial)
* provided a fast path implementation for "defaultmethod" * provided default system methods for "init", "defaultmethod" and "unknown" * provided handles for system methods "alloc", "dealloc", "recreate", and "defaultmethod" * strip in dispatch invocations of "unknown" potental leading colons * removed c-level implementation of init again, since scripted one can be used now as well in registration of createobjectsystem * reduced verbosity * added defintions such that these methods can be loaded via ::nsf::method::require ::nx::Object unknown
