- namespace changes: mostly due to marketing reasons, the naming of the top-level namespace changed from "xotcl2" to "next". reasons: xotcl is hard to pronounce for beginners, sounds like "exotic" (but who wants to program in an exotic language) has a certain stigma of strange namings (e.g. "instproc"), is seen as a precursor of tcloo, the top-level namespace ::xotcl2:: is not very nice either, the separation of framework and language is not clear. We have now: ::next (the new object system, former ::xotcl2) ::next::core (framework, primitives) ::xotcl (former xotcl1)
- "::xotcl::use" no longer needed, use Tcl standard mechanisms instead (e.g. "package req next"; "package req XOTcl", "namespace import ::next*")
- Handle cases, where objects/classes are created with the name of preexiting namespaces. Cases, where pre-exisitng namespaces contained classes/objects lead to problems, since xotcl did not see the object/classes of the pre-exiting namespace as children of the new object/class.
