Crash when returning primitive types

[robinwit]

dispatch_promise(^{
    return 3;
}).then(^(NSInteger i) {
    // …
});

This crashes here since the return type is obviously not id.
I don't know what's the cleanest way to solve this. It's kind of acceptable that primitive types don't work. Maybe even leave it as-is and update the docs, or start supporting it?

(I caught this when accidentally returning "string" instead of @"string". 🙈)

I actually can handle this, so I will. Let’s be delightful!

@mxcl Thought I'd throw my five cents in - if you don't mind a dependency on libffi, it is definitely possible to have primitive types as parameters as well. Like this!
