Dear Arthur,

What platform and what version are you using?

First of all, "nx::Class create ..." does not necessarily
create a namespace:

    $ ./nxsh
    % nx::Class create A {}
    ::A
    % proc ::A::new {} { return "something" }
    can't create procedure "::A::new": unknown namespace
        while executing
    "proc ::A::new {} { return "something" }"

When i create a class with a tcl namespace, i don't see
the problem either (using the head version)


   $ ./nxsh
   % nx::Class create A {:public class method foo args {}}
   ::A
    % proc ::A::new {} { return "something" }
    % rename ::A::new ""
    % A new
    ::nsf::__#0
