- 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.
- renaming of instance variable specific primitiva for more constistency with ::xotcl::importvar: ::xotcl::exists -> ::xotcl::existsvar ::xotcl::setinstvar -> ::xotcl::setvar
