Thanks for your hint. I already tried that. It doesn't work, because  
%attribute works like this:

%define %_attribute(Class, Wrap, type, attr, getcode, setcode)
%extend Class {
   type attr;
}
%{
#define Wrap ##_## attr ## _get(_t) getcode
#define Wrap ##_## attr ## _set(_t, _val) setcode
%}
%enddef

So it suffers the same problem when doing a manual %extend + static - the  
getters/setters are not called.
