I guess I also do not really get this. Sure JavaScript does not have a type system (yet?), but it seems that placing restrictions / coercion on input does not invalidate any of the properties of a map other than that there's a restriction on what goes in the map. To me that seems very much like a subset of a map and all generic functionality written around maps would work on such a map. -- http://annevankesteren.nl/ _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
