It would be useful if XPCOM had an any type that encapsualtes the basic types and nsISupports such that they can be treated uniformly. This would great for generic containers like property sets and bags e.g. see the corba property service: ftp://ftp.omg.org/pub/docs/formal/98-10-28.idl thus there is no need for 'application' specific interfaces with explicit get and set methods, or attributes (for explicit property names), for types. Two examples of where this would be useful are the preference and address book card areas. It might also make it easier for a Corba<->XPCOM bridge. Thanks, Paul.

This looks to be a dupe of bug 44675

reassign all kandrot xpcom bug.

Yes. This is a dup of bug 44675. I got distracted with other things, but I plan to have that code in soon. I hope other language mappings will follow my lead and add their own magic for nsIVariant support with short delay. This bug also touches on the need for a standard name/value pair collection feature that I've just filed as bug 98209. *** This bug has been marked as a duplicate of 44675 ***
