Sure. I shouldn't have caused a diversion about what goes in the spec. I have a reasonably clear picture of how to do it anyway. I am still curious how people write tests to evaluate the quality of weak references. Obviously you can expose lower-level, non-standard API's that provide metrics, but I wonder if there's any way to write standard code that tests weakly held data. I'm guessing there isn't. Again, this isn't pressing. Dave _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
