What is the expected evaluation order of the following snippet? Is it
"ABCXY" or
"ABXYC"? And can we have tests for it?
function* gen() { print('X'); yield 0; print('Y'); }
function a() { print('A'); }
function b() { print('B'); return gen(); }
function b() { print('C'); }
foo(a(), ...(b()), c());
This is a good test. I think `foo()` would be called with `[undefined,
0, undefined]`, and "ABXYC" should be printed. But interestingly, that's
not what happens (we get the expected arguments, but "ABCXY" is logged)
That is the behaviour in FF nightly, based on
http://jsfiddle.net/beumfrrm/
foo() would be called with arguments `[undefined, 0, undefined]`, and
"ABXYC" is printed. At least I think that's right :> adding test.
Adding the test and investigating that
