The yield keyword was previously only reserved in strict mode (ES5
7.6.1.2), which means it's perfectly valid JS to have: `function f() { var
yield = 1; return yield; }` in non-strict mode code. In order to allow
generator functions in both strict and non-strict code, where `yield` is a
keyword, a new syntactic form was needed, ie. the star (generator)
function. This avoids potentially breaking any existing code that is using
yield as an identifier.

I'm confident that it will not change.
