Getting infinite loop on ScopedDisposable.init about reactiveswift

Thanks for reporting the issue! This is definitely a bug.

Recommend changing the signature of the extension init to have a named argument, or even remove it? I'm not sure what the need for the extension init is, given that the normal init is fully generic already.

ScopedDisposable has the generic parameter of ScopedDisposable<InnerDisposable: Disposable>, but we can't pass an instance of Disposable protocol type itself because of the limitation of Swift generics. To initialize a ScopedDisposable we needed the new AnyDisposable and pass an instance of it. With the initializer we could write the code:

let d: Disposable = SimpleDisposable()
// `scoped` is `ScopedDisposable<AnyDisposable>`.
// We can't use `ScopedDisposable<Disposable>` in current Swift.
let scoped = ScopedDisposable(d)

I've submitted the fix: #23.
