this case is supported, seems, if to use:
function* b() {
return yield* a()
}

> What about the Timsort?
I cannot believe it will be faster on random int array. And TimSort is base on
MergeSort and, seems, for it's worst cases it cannot be better than MergeSort.
I have tried https://github.com/mziccard/node-timsort/ with my old node.js -
0.10.4 and Chrome 49 (win32) - and
@Tab Atkins Jr.,
The only question is how much slower/more expensiver stable sorting is than
unstable sorting, and whether that cost is sufficient to outweigh the
usefulness of a stable sort.
My own experiment shows, that QuickSort (unstable) is ~20% (or more) faster on
"random" array of intege

This will work only if `arr` is a copy of an array which you are trying to
sort, because the algorithm may swap those elements and so reposition them
relative to other elements ...
Stable sort is useful sometimes, but it is possible to

but according to spec, "forEach" should call callback with "-0":
var map = new Map();
map.set
