Let /map/ be the Map object that is the value of /O/’s [[BackingMap]] internal slot. ... 7. Let /function/ be the result of calling the [[Get]] internal method of /O/ passing /name/ and /O/ as arguments. Here, step 7 ought to call [[Get]] on /map/ from step 5, I think. Otherwise, step 7 would simply find the function that implements these steps. The same pattern repeats in the description of most maplike and setlike operations. Second, in "4.5.11.7. set" and "4.5.12.5. add and delete", the operations are ultimately defined as calling the corresponding function on the backing map/set and returning the result thereof. But Map.set() and Set.add() return the map/set object (i.e. 'this'), which thus would mean that e.g. a maplike platform object's set() operation would return the internal [[BackingMap]] object to the calling script code. It would seem more reasonable to return the maplike platform object, after calling the backing map's set(). 129578 1 Ms2ger 2019-02-28 13:21:34 +0000 Fixed in https://github.com/heycam/webidl/pull/47.
