| # Goals | |
| # | |
| # 1. Mix promise and non-promise arguments | |
| # 2. Behaves like a normal function if all arguments are non-promise | |
| # 3. Returns a promise if any non-promise argument | |
| # 4. Use no promise library, rely on the fact that: | |
| # promise.then(-> a1).then((a2) -> a1 === a2) | |
| # promise.then(-> Promise(a1)).then((a2) -> a1 === a2) | |
