Would it work to do:
  extends _TypedList with ListBase<int> implements Int8List
?
Or will that override some functions you don't want overridden?

Maybe
  extends ListBase<int> with _TypedList implements Int8List
(and remove all methods in TypedList that uses IterableMixinWorkaround)

[Florian Schneider, 2014/12/02 12:17:26]

In principle it would work. The down-side would be that every instance of typed
list would now have the type argument stored since the super class _TypedList
with _ListMixin<int> would have type arguments

With this approach (duplicating parts of ListMixin) we can get away without
actually storing type arguments in each object - saving one word per object.
