koher

I want Swift's Either like ...

Suppose that Either is declared in the following way,

enum Either<T, U> {
    case Left(T)
    case Right(U)
}

koher

a.map { b in
    b.map { c in {
        foo(b, c)
    }
}

for b in a {
    for c in b {
        foo(b, c)
    }

struct Array2<T> {
	var buffer: Buffer<T>
	var count: Int
	
	init() {

	init(_ elements: T...) {
