The function in question looks like this

func toArray<E, T: AsArray<E>>(env: Scope, coercion: T) throws -> T.SwiftType

and I don't think Swift supports that AsArray<E> as a constraint yet. However, since you don't have any subclasses of AsArray, you can simplify this to

func toArray<E>(env: Scope, coercion: AsArray<E>) throws -> AsArray<E>.SwiftType
