which is strange, considering the `async` keyword in upcoming versions.

  That's why it wasn't included in the ecmascript 6 draft. In es6, "async" and "await" are future-reserved keywords. It's kind of a process of marking variables named "async" as deprecated. The spec authors have to balance compatibility with making the language pleasant to use.

  Is there even any situation where "async function(..." or "generator function(..." is currently valid syntax?

  AFAICT, `async function` is OK, because you combine a keyword with something that is contextually turned into a keyword. With a single non-keyword that isn’t possble. For example, the following code (a hypothetical ES6 anonymous generator expression) could be an ES5 function call followed by a code block. generator (a, b, c) { ··· }
