-The ''void'' name (in any combination of case) should be reserved in class, interface and trait name contextsbecause this is a likely candidate for the demarcation of void functions (which do not return a value). Alternatively ''null'' can be used for this purpose, which is already reserved. However both possibilities should be kept open until we reach a decision on this question.+**Where**: As the last segment of class, interface or trait name. As such the names ''Void'' and ''Foo\Bar\Void'' are reservedwhile ''Foo\Bar\MyVoid'' and ''Void\Foo\Bar'' are okay.
