for (let i of new F) {} not valid syntax?

[raul.m...@gmail.com]

Hello,

If I write

<code>

class C {

* [Symbol.iterator]() {

yield 1;

yield 2;

yield 3;

    }

}

for (let i of new C) {

console.log(i);

}

</code>

without adding the parentheses where I'm calling new C, I get "undefined is not a function".

The same if I write

<code>

function F() {

return (function *() {

yield 1;

yield 2;

})();

}

for (let i of new F) {

console.log(i);

}

</code>

If I add the parentheses it's OK.

Is the syntax without parentheses wrong in for-of?

Thank you,

Raul

I see that in FF, the second example works, but I don't know how up to date FF is.

This is a bug in Traceur. We need to add parens.
