Since ECMAScript 4 proposed generators without using a `*` prefix in
function names unlike in ECMAScript Harmony, I suggest, please... maybe do not
introduce the `async` modifier and comply with ECMAScript 4?
Not that it's difficult to parse, but it'd be nice to have a general
consensus in the syntax, since ActionScript 3.0 implements most of ECMAScript 4.
ES4 examples:
```
/* methodThatYields(): Iterator.<Number> */
function methodThatYields(): Number {
for (var i = 0; i < 10; i++) {
yield i
}
}
```
Example of asynchronous methods as in
[AS3Parser](https://github.com/hydroper/as3parser):
```
function asynchronousMethod1(): Promise.<Number> (
Promise.resolve(10)
);
function asynchronousMethod2(): Promise.<Number> {
return await asynchronousMethod1();
}
```
I've an implementation of `Promise` in my repository, as well (based on a
polyfill), but I added a simple type parameter, so you may want to look at
[agera.util](https://github.com/agera-air/util) instead.
