Description Boris Zbarsky 2012-07-27 01:45:13 UTC
Consider this IDL:

  dictionary Dict1 {
    Dict2 member;
  };
  dictionary Dict2 : Dict1 {
  };

or even simpler:

  dictionary Dict1 {
    Dict1 member;
  };

This should probably be disallowed, since there's no sane way to do it.

I've disallowed all direct and indirect references to the same dictionary:
