In Episode #13 The Many Faces of Map.

func map<A, B>(_ f: @escaping (A) -> B) -> ([A]) -> [B] {
return { xs in
var result = B
xs.forEach {
result.append(f($0))
}
return result
}
}

I found: [1, 2, 3] |> map(incr)

what is |> ?
why is not a . (dot) ?
is there another symbols combinations like this?

And this? : >>>

[1, 2, 3] |> map(incr) |> map(square)
[1, 2, 3] |> map(incr >>> square)

Thanks
