Sorry, that was unclear: I meant the indirection through .constructor was a complexity, not the substituted object return value which applies to both approaches. > Especially for abstractions that want to be callable without 'new' to > construct a new instance (Array, e.g.). This is a crucial case. User-defined functions can be new'ed or invoked without new. They have .prototypes. None of this is going away. /be _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
