I think changing things right now is the wrong thing to do. Since this
is a compatible extension, we don't have to think about this for ES6.
Just putting that out there ;)
That said, first thoughts:
* I assume "input" could then be captured by nested scopes. This
would be a bit strange but could work.
* Really you'd want to be able to destructure too, as you can in every
other part of the grammar that introduces names. That's probably
not a great thing to do here, though.
* I assume Kevin meant:
function *echo input { while (true) yield input }
To me it smells, but perhaps that is just my grumpiness ;)
Explicitly being able to place the initial yield would be nicer, but
then it's more difficult to ensure that the initial yield comes before
other yields.
I say punt ;)
