In Dylan this conundrum is dealt with either by interning (which could be done in JS by returning an existing object from the constructor), or by overriding == (Which is easy in Dylan because == is an open multi-method that can be extended by libraries, not yet in JS). http://www.opendylan.org/books/dpg/db_346.html _______________________________________________ Es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
