[next] _DOMStringMap computes keys and values eagerly #7956

Open floitschG opened 11 years ago

floitschG commented 11 years ago

The current implementation of _DOMStringMap computes the keys and values eagerly. It should compute them lazily. The behavior is undefined if the map is changed during iteration, but only when an "iterator" is actually in use. For example: var map = new Map(); var keys = map.keys; map["foo"] = 499; // legal. for (var x = in keys) print(x); // prints "499". map["bar"] = 42; for (var x = in keys) {   map["toto"] = -1; // bad. Mutation not allowed while iterating. }

Might get addressed by Terry's work.
