Not a bug.

The '::' operator (if you can call it that) is used to call the
inherited function, inside the auto-object that just means the kfun
version effectively.  The '::' operator does not try more than one
possibility, there is no ambiguity in what it's going to do.

If you inherit objects 'foo.c' and 'bar.c' and both define a function
called 'blah()', you need to label the inherited objects, DGD does not
use implicit labeling, and redefine blah() to call one or the other,
whichever you think is appropriate.  For instance:

  inherit o_foo "foo";
  inherit o_bar "bar";

  void blah() {
    o_foo :: blah();
    o_bar :: blah();
  }

Hope this helps,

Erwin.
