And in ES6 as amended, this should just be:

     console.log(yield);

Yield (after return, but return is a statement form, of course -- yield 
is an expression form due to send) can have an operand on its right, or 
no operand (meaning yield undefined). Cc'ing Allen to double-check that 
the spec will say so.
