We're speaking too broadly here. It depends on what we want to work how. For example, .map can't magically know how to produce a SubArray as its result if that's how SubArray wants it to work. But what I'm actually more concerned about is the behavior of .length. Does the <| semantics make .length work automagically the way it does for ordinary Array instances? > However, subarray instances have all the internal state and methods that make > them true arrays so even if some of the inherited Array methods weren't > generic they would still work. Including .length (which isn't a method, but YKWIM)? Dave _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
