List.sort's one parameter can now be optional

[sethladd]

I see the Comparable.compare is a static method you can give to sort:

main() {
  var fruits = <String>['bananas', 'apples', 'oranges'];
  fruits.sort(Comparable.compare);
  print(fruits);
}

It would be nice to make sort's parameter optional, and use Comparable.compare if a parameter is not provided:

sort([Comparator comparator]) // use Comparable.compare if no comparator is given

Then we can so this:

fruits.sort();

Which is a common case.

That was exactly the point of introducing Comparable.compare.
It will happen.
The problem that blocked it might not be relevant anyway.
