We could have a promise(fn) method which returns a promise, and calls the function with the resolver for that promise.

Advantages

• discoverable via .constructor property of a promise (see discovery of resolver #5)
• supports prototypal inheritance (see Extended promise objects #6)
• consistent with other promise-creation

Disadvantages

• Increased nesting
• Extra function keyword
• deffereds will receive a lot less hate once we have ES6

Summary

I'm very much in favour of this proposal
