Details

In writing new JS module code for ArrayConverter (bug 380839), I noticed my module's ArrayConverter.nsIArray() method could not evaluate "(aArray instanceof Array)" to true under any circumstances. For the native types, such as Array, Object, etc., it would be nice to have that evaluate to true when appropriate, so that I could throw an exception if it wasn't true. I wonder if this bug is fundamentally a dupe of bug 339884. I can provide a xpcshell testcase if so desired for components (I suspect the same bug may apply across XPCOM component boundaries).
